-@section Error reporting
-Most BFD functions return nonzero on success (check their
-individual documentation for precise semantics). On an error,
-they call @code{bfd_set_error} to set an error condition that callers
-can check by calling @code{bfd_get_error}.
-If that returns @code{bfd_error_system_call}, then check
-@code{errno}.
-
-The easiest way to report a BFD error to the user is to
-use @code{bfd_perror}.
-@*
-@subsection Type @code{bfd_error_type}
-The values returned by @code{bfd_get_error} are defined by the
-enumerated type @code{bfd_error_type}.
-@*
-.
-@example
-typedef enum bfd_error
-@{
- bfd_error_no_error = 0,
- bfd_error_system_call,

-@strong{Description}@*
-Print to the standard error stream a string describing the
-last BFD error that occurred, or the last system error if
-the last BFD error was a system call failure. If @var{message}
-is non-NULL and non-empty, the error string printed is preceded
-by @var{message}, a colon, and a space. It is followed by a newline.
-@*
-@subsection BFD error handler
-Some BFD functions want to print messages describing the
-problem. They call a BFD error handler function. This
-function may be overriden by the program.
-
-The BFD error handler acts like printf.
-@*
-.
-@example
-typedef void (*bfd_error_handler_type) PARAMS ((const char *, ...));

-@end example
-@findex bfd_set_error_handler
-@subsubsection @code{bfd_set_error_handler}
-@strong{Synopsis}
-@example
-bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type);

-@example
-void bfd_set_error_program_name (const char *);
-@end example
-@strong{Description}@*
-Set the program name to use when printing a BFD error. This
-is printed before the error message followed by a colon and
-space. The string must not be changed after it is passed to
-this function.

-@end example
-@strong{Description}@*
-Call the back end associated with the open BFD
-@var{abfd} and translate the external form of the relocation
-information attached to @var{sec} into the internal canonical
-form. Place the table into memory at @var{loc}, which has
-been preallocated, usually by a call to
-@code{bfd_get_reloc_upper_bound}. Returns the number of relocs, or
--1 on error.
-
-The @var{syms} table is also needed for horrible internal magic
-reasons.

-@strong{Description}@*
-Set the flag word in the BFD @var{abfd} to the value @var{flags}.
-
-Possible errors are:
-@itemize @bullet

-@item
-@code{bfd_error_wrong_format} - The target bfd was not of object format.
-@item
-@code{bfd_error_invalid_operation} - The target bfd was open for reading.
-@item
-@code{bfd_error_invalid_operation} -
-The flag word contained a bit which was not applicable to the
-type of file. E.g., an attempt was made to set the @code{D_PAGED} bit
-on a BFD format which does not support demand paging.

-@findex bfd_get_mtime
-@subsubsection @code{bfd_get_mtime}
-@strong{Synopsis}
-@example
-long bfd_get_mtime(bfd *abfd);
-@end example
-@strong{Description}@*
-Return the file modification time (as read from the file system, or
-from the archive header for archive members).
-@*
-@findex bfd_get_size
-@subsubsection @code{bfd_get_size}
-@strong{Synopsis}
-@example
-long bfd_get_size(bfd *abfd);
-@end example
-@strong{Description}@*
-Return the file size (as read from file system) for the file
-associated with BFD @var{abfd}.
-
-The initial motivation for, and use of, this routine is not
-so we can get the exact size of the object the BFD applies to, since
-that might not be generally possible (archive members for example).
-It would be ideal if someone could eventually modify
-it so that such results were guaranteed.
-
-Instead, we want to ask questions like "is this NNN byte sized
-object I'm about to try read from file offset YYY reasonable?"
-As as example of where we might do this, some object formats
-use string tables for which the first @code{sizeof(long)} bytes of the
-table contain the size of the table itself, including the size bytes.
-If an application tries to read what it thinks is one of these
-string tables, without some way to validate the size, and for
-some reason the size is wrong (byte swapping error, wrong location
-for the string table, etc.), the only clue is likely to be a read
-error when it tries to read the table, or a "virtual memory
-exhausted" error when it tries to allocate 15 bazillon bytes
-of space for the 15 bazillon byte table it is about to read.
-This function at least allows us to answer the quesion, "is the
-size reasonable?".

-bfd_vma bfd_scan_vma(CONST char *string, CONST char **end, int base);
-@end example
-@strong{Description}@*
-Convert, like @code{strtoul}, a numerical expression
-@var{string} into a @code{bfd_vma} integer, and return that integer.
-(Though without as many bells and whistles as @code{strtoul}.)
-The expression is assumed to be unsigned (i.e., positive).
-If given a @var{base}, it is used as the base for conversion.
-A base of 0 causes the function to interpret the string
-in hex if a leading "0x" or "0X" is found, otherwise
-in octal if a leading zero is found, otherwise in decimal.

-.TH GROTTY @MAN1EXT@ "@MDATE@" "Groff Version @VERSION@"
-.SH NAME
-grotty \- groff driver for typewriter-like devices
-.SH SYNOPSIS
-.B grotty
-[
-.B \-hfbuodBUv
-] [
-.BI \-F dir
-] [
-.IR files \|.\|.\|.
-]
-.SH DESCRIPTION
-.B grotty
-translates the output of GNU
-.B troff
-into a form suitable for typewriter-like devices.
-Normally
-.B grotty
-should invoked by using the
-.B groff
-command
-with a
-.BR \-Tascii ,
-.B \-Tkoi8-r
-or
-.B \-Tlatin1
-option.
-If no files are given,
-.B grotty
-will read the standard input.
-A filename of
-.B \-
-will also cause
-.B grotty
-to read the standard input.
-Output is written to the standard output.
-.LP
-Normally
-.B grotty
-prints a bold character
-.I c
-using the sequence
-.RI ` c
-.SM BACKSPACE
-.IR c '
-and a italic character
-.I c
-by the sequence
-.RB ` _
-.SM BACKSPACE
-.IR c '.
-These sequences can be displayed on a terminal
-by piping through
-.BR ul (1).
-Pagers such as
-.BR more (1)
-or
-.BR less (1)
-are also able to display these sequences.
-Use either
-.B \-B
-or
-.B \-U
-when piping into
-.BR less (1);
-use
-.B \-b
-when piping into
-.BR more (1).
-There is no need to filter the output through
-.BR col (1)
-since
-.B grotty
-never outputs reverse line feeds.
-.LP
-The font description file may contain a command
-.IP
-.BI internalname\ n
-.LP
-where
-.I n
-is a decimal integer.
-If the 01 bit in
-.I n
-is set,
-then the font will be treated as an italic font;
-if the 02 bit is set,
-then it will be treated as a bold font.
-The code field in the font description field gives the
-code which will be used to output the character.
-This code can also be used in the
-.B \eN
-escape sequence in
-.BR troff .
-.SH OPTIONS
-.TP
-.BI \-F dir
-Search the directory
-.IB dir /dev name
-for font and device description files;
-.I name
-is the name of the device, usually
-.BR ascii ,
-.B koi8-r
-or
-.BR latin1 .
-.TP
-.B \-h
-Use horizontal tabs in the output.
-Tabs are assumed to be set every 8 columns.
-.TP
-.B \-f
-Use form feeds in the output.
-A form feed will be output at the end of each page that has no output
-on its last line.
-.TP
-.B \-b
-Suppress the use of overstriking for bold characters.
-.TP
-.B \-u
-Suppress the use of underlining for italic characters.
-.TP
-.B \-B
-Use only overstriking for bold-italic characters.
-.TP
-.B \-U
-Use only underlining for bold-italic characters.
-.TP
-.B \-o
-Suppress overstriking (other than for bold or underlined characters).
-.TP
-.B \-d
-Ignore all
-.B \eD
-commands.
-Without this
-.B grotty
-will render
-.B \eD'l\|.\|.\|.'
-commands that have at least at least one zero argument
-(and so are either horizontal or vertical)
-using
-.BR \- ,
-.B |
-and
-.B +
-characters.
-.TP
-.B \-v
-Print the version number.
-.SH FILES
-.TP
-.B @FONTDIR@/dev\fIname\fB/DESC
-Device description file for
-.I name
-device.
-.TP
-.BI @FONTDIR@/dev\fIname\fB/ F
-Font description file for font
-.I F
-of
-.I name
-device.
-.TP
-.B @MACRODIR@/tmac.tty
-Macros for use with
-.BR grotty .
-.TP
-.B @MACRODIR@/tmac.tty-char
-Additional klugey character definitions for use with
-.BR grotty .
-.SH BUGS
-.LP
-.B grotty
-is intended only for simple documents.
-.LP
-There is no support for fractional horizontal or vertical motions.
-.LP
-There is no support for
-.B \eD
-commands
-other than horizontal and vertical lines.
-.LP
-Characters above the first line (ie with a vertical position of 0)
-cannot be printed.

-.SH DESCRIPTION
-.B groff
-is a front-end to the groff document formatting system.
-Normally it runs the
-.B @g@troff
-program and a postprocessor appropriate for the selected
-device.
-Available devices are:
-.TP
-.B ps
-For PostScript printers and previewers
-.TP
-.B dvi
-For TeX dvi format
-.TP
-.B X75
-For a 75 dpi X11 previewer
-.TP
-.B X100
-For a 100dpi X11 previewer
-.TP
-.B ascii
-For typewriter-like devices
-.TP
-.B latin1
-For typewriter-like devices using the ISO Latin-1 character set.
-.TP
-.B koi8-r
-For typewriter-like devices using the russian KOI8-R character set.
-.LP
-The postprocessor to be used for a device is specified by the
-.B postpro
-command in the device description file.
-This can be overridden with the
-.B \-X
-option.
-.LP
-The default device is
-.BR @DEVICE@ .
-It can optionally preprocess with any of
-.BR @g@pic ,
-.BR @g@eqn ,
-.BR @g@tbl ,
-.BR @g@refer ,
-or
-.B @g@soelim.
-.LP
-Options without an argument can be grouped behind a single
-.BR \- .
-A filename of
-.B \-
-denotes the standard input.
-.LP
-The
-.B grog
-command can be used to guess the correct groff command to use to
-format a file.
-.SH OPTIONS
-.TP
-.B \-h
-Print a help message.
-.TP
-.B \-e
-Preprocess with @g@eqn.
-.TP
-.B \-t
-Preprocess with @g@tbl.
-.TP
-.B \-p
-Preprocess with @g@pic.
-.TP
-.B \-s
-Preprocess with @g@soelim.
-.TP
-.B \-R
-Preprocess with @g@refer.
-No mechanism is provided for passing arguments to
-.B @g@refer
-because most @g@refer options have equivalent commands
-which can be included in the file.
-See
-.BR @g@refer (@MAN1EXT@)
-for more details.
-.TP
-.B \-v
-Make programs run by
-.B groff
-print out their version number.
-.TP
-.B \-V
-Print the pipeline on stdout instead of executing it.
-.TP
-.B \-z
-Suppress output from
-.BR @g@troff .
-Only error messages will be printed.
-.TP
-.B \-Z
-Do not postprocess the output of
-.BR @g@troff .
-Normally
-.B groff
-will automatically run the appropriate postprocessor.
-.TP
-.BI \-P arg
-Pass
-.I arg
-to the postprocessor.
-Each argument should be passed with a separate
-.B \-P
-option.
-Note that
-.B groff
-does not prepend
-.B \-
-to
-.I arg
-before passing it to the postprocessor.
-.TP
-.B \-l
-Send the output to a printer.
-The command used for this is specified by the
-.B print
-command in the device description file.
-.TP
-.BI \-L arg
-Pass
-.I arg
-to the spooler.
-Each argument should be passed with a separate
-.B \-L
-option.
-Note that
-.B groff
-does not prepend
-.B \-
-to
-.I arg
-before passing it to the postprocessor.
-.TP
-.BI \-T dev
-Prepare output for device
-.IR dev .
-The default device is
-.BR @DEVICE@ .
-.TP
-.B \-X
-Preview with
-.B gxditview
-instead of using the usual postprocessor.
-.B Groff
-passes
-.B gxditview
-a
-.B -printCommand
-option which will make the
-.B Print
-action do what
-.B groff
-would have done if the
-.B -l
-option had been given.
-This is unlikely to produce good results except with
-.BR \-Tps .
-.TP
-.B \-N
-Don't allow newlines with eqn delimiters.
-This is the same as the
-.B \-N
-option in
-.BR @g@eqn .
-.TP
-.B \-S
-Safer mode. Pass the
-.B \-S
-option to
-.B @g@pic
-and use the
-.B \%\-msafer
-macros with
-.BR @g@troff .

-.SH DESCRIPTION
-.LP
-.B readline
-will read a line from the terminal
-and return it, using
-.B prompt
-as a prompt. If
-.B prompt
-is null, no prompt is issued. The line returned is allocated with
-.IR malloc (3),
-so the caller must free it when finished. The line returned
-has the final newline removed, so only the text of the line
-remains.
-.LP
-.B readline
-offers editing capabilities while the user is entering the
-line.
-By default, the line editing commands
-are similar to those of emacs.
-A vi\-style line editing interface is also available.
-.SH RETURN VALUE
-.LP
-.B readline
-returns the text of the line read. A blank line
-returns the empty string. If
-.B EOF
-is encountered while reading a line, and the line is empty,
-.B NULL
-is returned. If an
-.B EOF
-is read with a non\-empty line, it is
-treated as a newline.
-.SH NOTATION
-.LP
-An emacs-style notation is used to denote
-keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n
-means Control\-N. Similarly,
-.I meta
-keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards
-without a
-.I meta
-key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key
-then the
-.I x
-key. This makes ESC the \fImeta prefix\fP.
-The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP,
-or press the Escape key
-then hold the Control key while pressing the
-.I x
-key.)
-.PP
-Readline commands may be given numeric
-.IR arguments ,
-which normally act as a repeat count. Sometimes, however, it is the
-sign of the argument that is significant. Passing a negative argument
-to a command that acts in the forward direction (e.g., \fBkill\-line\fP)
-causes that command to act in a backward direction. Commands whose
-behavior with arguments deviates from this are noted.
-.PP
-When a command is described as \fIkilling\fP text, the text
-deleted is saved for possible future retrieval
-(\fIyanking\fP). The killed text is saved in a
-\fIkill ring\fP. Consecutive kills cause the text to be
-accumulated into one unit, which can be yanked all at once.
-Commands which do not kill text separate the chunks of text
-on the kill ring.
-.SH INITIALIZATION FILE
-.LP
-Readline is customized by putting commands in an initialization
-file (the \fIinputrc\fP file).
-The name of this file is taken from the value of the
-.B INPUTRC
-environment variable. If that variable is unset, the default is
-.IR ~/.inputrc .
-When a program which uses the readline library starts up, the
-init file is read, and the key bindings and variables are set.
-There are only a few basic constructs allowed in the
-readline init file. Blank lines are ignored.
-Lines beginning with a \fB#\fP are comments.
-Lines beginning with a \fB$\fP indicate conditional constructs.
-Other lines denote key bindings and variable settings.
-Each program using this library may add its own commands
-and bindings.
-.PP
-For example, placing
-.RS
-.PP
-M\-Control\-u: universal\-argument
-.RE
-or
-.RS
-C\-Meta\-u: universal\-argument
-.RE
-into the
-.I inputrc
-would make M\-C\-u execute the readline command
-.IR universal\-argument .
-.PP
-The following symbolic character names are recognized while
-processing key bindings:
-.IR RUBOUT ,
-.IR DEL ,
-.IR ESC ,
-.IR LFD ,
-.IR NEWLINE ,
-.IR RET ,
-.IR RETURN ,
-.IR SPC ,
-.IR SPACE ,
-and
-.IR TAB .
-In addition to command names, readline allows keys to be bound
-to a string that is inserted when the key is pressed (a \fImacro\fP).
-.PP
-.SS Key Bindings
-.PP
-The syntax for controlling key bindings in the
-.I inputrc
-file is simple. All that is required is the name of the
-command or the text of a macro and a key sequence to which
-it should be bound. The name may be specified in one of two ways:
-as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP
-prefixes, or as a key sequence.
-When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP,
-.I keyname
-is the name of a key spelled out in English. For example:
-.sp
-.RS
-Control\-u: universal\-argument
-.br
-Meta\-Rubout: backward\-kill\-word
-.br
-Control\-o: ">&output"
-.RE
-.LP
-In the above example,
-.I C\-u
-is bound to the function
-.BR universal\-argument ,
-.I M-DEL
-is bound to the function
-.BR backward\-kill\-word ,
-and
-.I C\-o
-is bound to run the macro
-expressed on the right hand side (that is, to insert the text
-.I >&output
-into the line).
-.PP
-In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP,
-.B keyseq
-differs from
-.B keyname
-above in that strings denoting
-an entire key sequence may be specified by placing the sequence
-within double quotes. Some GNU Emacs style key escapes can be
-used, as in the following example.
-.sp
-.RS
-"\eC\-u": universal\-argument
-.br
-"\eC\-x\eC\-r": re\-read\-init\-file
-.br
-"\ee[11~": "Function Key 1"
-.RE
-.PP
-In this example,
-.I C-u
-is again bound to the function
-.BR universal\-argument .
-.I "C-x C-r"
-is bound to the function
-.BR re\-read\-init\-file ,
-and
-.I "ESC [ 1 1 ~"
-is bound to insert the text
-.BR "Function Key 1" .
-The full set of GNU Emacs style escape sequences is
-.RS
-.PD 0
-.TP
-.B \eC\-
-control prefix
-.TP
-.B \eM\-
-meta prefix
-.TP
-.B \ee
-an escape character
-.TP
-.B \e\e
-backslash
-.TP
-.B \e"
-literal "
-.TP
-.B \e'
-literal '
-.RE
-.PD
-.PP
-In addition to the GNU Emacs style escape sequences, a second
-set of backslash escapes is available:
-.RS
-.PD 0
-.TP
-.B \ea
-alert (bell)
-.TP
-.B \eb
-backspace
-.TP
-.B \ed
-delete
-.TP
-.B \ef
-form feed
-.TP
-.B \en
-newline
-.TP
-.B \er
-carriage return
-.TP
-.B \et
-horizontal tab
-.TP
-.B \ev
-vertical tab
-.TP
-.B \e\fInnn\fP
-the character whose ASCII code is the octal value \fInnn\fP
-(one to three digits)
-.TP
-.B \ex\fInnn\fP
-the character whose ASCII code is the hexadecimal value \fInnn\fP
-(one to three digits)
-.RE
-.PD
-.PP
-When entering the text of a macro, single or double quotes should
-be used to indicate a macro definition. Unquoted text
-is assumed to be a function name.
-In the macro body, the backslash escapes described above are expanded.
-Backslash will quote any other character in the macro text,
-including " and '.
-.PP
-.B Bash
-allows the current readline key bindings to be displayed or modified
-with the
-.B bind
-builtin command. The editing mode may be switched during interactive
-use by using the
-.B \-o
-option to the
-.B set
-builtin command. Other programs using this library provide
-similar mechanisms. The
-.I inputrc
-file may be edited and re-read if a program does not provide
-any other means to incorporate new bindings.
-.SS Variables
-.PP
-Readline has variables that can be used to further customize its
-behavior. A variable may be set in the
-.I inputrc
-file with a statement of the form
-.RS
-.PP
-\fBset\fP \fIvariable\-name\fP \fIvalue\fP
-.RE
-.PP
-Except where noted, readline variables can take the values
-.B On
-or
-.BR Off .
-The variables and their default values are:
-.PP
-.PD 0
-.TP
-.B bell\-style (audible)
-Controls what happens when readline wants to ring the terminal bell.
-If set to \fBnone\fP, readline never rings the bell. If set to
-\fBvisible\fP, readline uses a visible bell if one is available.
-If set to \fBaudible\fP, readline attempts to ring the terminal's bell.
-.TP
-.B comment\-begin (``#'')
-The string that is inserted in \fBvi\fP mode when the
-.B insert\-comment
-command is executed.
-This command is bound to
-.B M\-#
-in emacs mode and to
-.B #
-in vi command mode.
-.TP
-.B completion\-ignore\-case (Off)
-If set to \fBOn\fP, readline performs filename matching and completion
-in a case\-insensitive fashion.
-.TP
-.B completion\-query\-items (100)
-This determines when the user is queried about viewing
-the number of possible completions
-generated by the \fBpossible\-completions\fP command.
-It may be set to any integer value greater than or equal to
-zero. If the number of possible completions is greater than
-or equal to the value of this variable, the user is asked whether
-or not he wishes to view them; otherwise they are simply listed
-on the terminal.
-.TP
-.B convert\-meta (On)
-If set to \fBOn\fP, readline will convert characters with the
-eighth bit set to an ASCII key sequence
-by stripping the eighth bit and prepending an
-escape character (in effect, using escape as the \fImeta prefix\fP).
-.TP
-.B disable\-completion (Off)
-If set to \fBOn\fP, readline will inhibit word completion. Completion
-characters will be inserted into the line as if they had been
-mapped to \fBself-insert\fP.
-.TP
-.B editing\-mode (emacs)
-Controls whether readline begins with a set of key bindings similar
-to \fIemacs\fP or \fIvi\fP.
-.B editing\-mode
-can be set to either
-.B emacs
-or
-.BR vi .
-.TP
-.B enable\-keypad (Off)
-When set to \fBOn\fP, readline will try to enable the application
-keypad when it is called. Some systems need this to enable the
-arrow keys.
-.TP
-.B expand\-tilde (Off)
-If set to \fBon\fP, tilde expansion is performed when readline
-attempts word completion.
-.TP
-.B horizontal\-scroll\-mode (Off)
-When set to \fBOn\fP, makes readline use a single line for display,
-scrolling the input horizontally on a single screen line when it
-becomes longer than the screen width rather than wrapping to a new line.
-.TP
-.B keymap (emacs)
-Set the current readline keymap. The set of legal keymap names is
-\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
-vi-command\fP, and
-.IR vi-insert .
-\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is
-equivalent to \fIemacs-standard\fP. The default value is
-.IR emacs ;
-the value of
-.B editing\-mode
-also affects the default keymap.
-.TP
-.B mark\-directories (On)
-If set to \fBOn\fP, complete<d directory names have a slash
-appended.
-.TP
-.B mark\-modified\-lines (Off)
-If set to \fBOn\fP, history lines that have been modified are displayed
-with a preceding asterisk (\fB*\fP).
-.TP
-.B meta\-flag (Off)
-If set to \fBOn\fP, readline will enable eight-bit input (that is,
-it will not strip the high bit from the characters it reads),
-regardless of what the terminal claims it can support.
-.TP
-.B output\-meta (Off)
-If set to \fBOn\fP, readline will display characters with the
-eighth bit set directly rather than as a meta-prefixed escape
-sequence.
-.TP
-.B print\-completions\-horizontally (Off)
-If set to \fBOn\fP, readline will display completions with matches
-sorted horizontally in alphabetical order, rather than down the screen.
-.TP
-.B show\-all\-if\-ambiguous (Off)
-This alters the default behavior of the completion functions. If
-set to
-.BR on ,
-words which have more than one possible completion cause the
-matches to be listed immediately instead of ringing the bell.
-.TP
-.B visible\-stats (Off)
-If set to \fBOn\fP, a character denoting a file's type as reported
-by \fBstat\fP(2) is appended to the filename when listing possible
-completions.
-.PD
-.SS Conditional Constructs
-.PP
-Readline implements a facility similar in spirit to the conditional
-compilation features of the C preprocessor which allows key
-bindings and variable settings to be performed as the result
-of tests. There are four parser directives used.
-.IP \fB$if\fP
-The
-.B $if
-construct allows bindings to be made based on the
-editing mode, the terminal being used, or the application using
-readline. The text of the test extends to the end of the line;
-no characters are required to isolate it.
-.RS
-.IP \fBmode\fP
-The \fBmode=\fP form of the \fB$if\fP directive is used to test
-whether readline is in emacs or vi mode.
-This may be used in conjunction
-with the \fBset keymap\fP command, for instance, to set bindings in
-the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if
-readline is starting out in emacs mode.
-.IP \fBterm\fP
-The \fBterm=\fP form may be used to include terminal-specific
-key bindings, perhaps to bind the key sequences output by the
-terminal's function keys. The word on the right side of the
-.B =
-is tested against the full name of the terminal and the portion
-of the terminal name before the first \fB\-\fP. This allows
-.I sun
-to match both
-.I sun
-and
-.IR sun\-cmd ,
-for instance.
-.IP \fBapplication\fP
-The \fBapplication\fP construct is used to include
-application-specific settings. Each program using the readline
-library sets the \fIapplication name\fP, and an initialization
-file can test for a particular value.
-This could be used to bind key sequences to functions useful for
-a specific program. For instance, the following command adds a
-key sequence that quotes the current or previous word in Bash:
-.sp 1
-.RS
-.nf
-\fB$if\fP bash
-# Quote the current or previous word
-"\eC-xq": "\eeb\e"\eef\e""
-\fB$endif\fP
-.fi
-.RE
-.RE
-.IP \fB$endif\fP
-This command, as seen in the previous example, terminates an
-\fB$if\fP command.
-.IP \fB$else\fP
-Commands in this branch of the \fB$if\fP directive are executed if
-the test fails.
-.IP \fB$include\fP
-This directive takes a single filename as an argument and reads commands
-and bindings from that file. For example, the following directive
-would read \fI/etc/inputrc\fP:
-.sp 1
-.RS
-.nf
-\fB$include\fP \^ \fI/etc/inputrc\fP
-.fi
-.RE
-.SH SEARCHING
-.PP
-Readline provides commands for searching through the command history
-for lines containing a specified string.
-There are two search modes:
-.I incremental
-and
-.IR non-incremental .
-.PP
-Incremental searches begin before the user has finished typing the
-search string.
-As each character of the search string is typed, readline displays
-the next entry from the history matching the string typed so far.
-An incremental search requires only as many characters as needed to
-find the desired history entry.
-The Escape character is used to terminate an incremental search.
-Control-J will also terminate the search.
-Control-G will abort an incremental search and restore the original
-line.
-When the search is terminated, the history entry containing the
-search string becomes the current line.
-To find other matching entries in the history list, type Control-S or
-Control-R as appropriate.
-This will search backward or forward in the history for the next
-line matching the search string typed so far.
-Any other key sequence bound to a readline command will terminate
-the search and execute that command.
-For instance, a \fInewline\fP will terminate the search and accept
-the line, thereby executing the command from the history list.
-.PP
-Non-incremental searches read the entire search string before starting
-to search for matching history lines. The search string may be
-typed by the user or be part of the contents of the current line.
-.SH EDITING COMMANDS
-.PP
-The following is a list of the names of the commands and the default
-key sequences to which they are bound.
-Command names without an accompanying key sequence are unbound by default.

-.SS Commands for Manipulating the History
-.PP
-.PD 0
-.TP
-.B accept\-line (Newline, Return)
-Accept the line regardless of where the cursor is. If this line is

-entered.
-.TP
-.B reverse\-search\-history (C\-r)
-Search backward starting at the current line and moving `up' through
-the history as necessary. This is an incremental search.
-.TP
-.B forward\-search\-history (C\-s)

-This is a non-incremental search.
-.TP
-.B yank\-nth\-arg (M\-C\-y)
-Insert the first argument to the previous command (usually
-the second word on the previous line) at point (the current
-cursor position). With an argument
-.IR n ,
-insert the \fIn\fPth word from the previous command (the words

-list, inserting the last argument of each line in turn.
-.PD
-.SS Commands for Changing Text
-.PP
-.PD 0
-.TP
-.B delete\-char (C\-d)
-Delete the character under the cursor. If point is at the
-beginning of the line, there are no characters in the line, and
-the last character typed was not bound to \fBBdelete\-char\fP, then return
-.SM
-.BR EOF .
-.TP
-.B backward\-delete\-char (Rubout)
-Delete the character behind the cursor. When given a numeric argument,
-save the deleted text on the kill ring.
-.TP
-.B quoted\-insert (C\-q, C\-v)

-.TP
-.B self\-insert (a,\ b,\ A,\ 1,\ !,\ ...)
-Insert the character typed.
-.TP

-Drag the word behind the cursor past the word in front of the cursor
-moving the cursor over that word as well.
-.TP

-The killed text is saved on the kill-ring.
-.\" There is no real difference between this and backward-kill-line
-.TP
-.B kill\-whole\-line
-Kill all characters on the current line, no matter where the
-cursor is.
-.TP
-.B kill\-word (M\-d)
-Kill from the cursor to the end of the current word, or if between
-words, to the end of the next word. Word boundaries are the same as
-those used by \fBforward\-word\fP.
-.TP
-.B backward\-kill\-word (M\-Rubout)
-Kill the word behind the cursor. Word boundaries are the same as
-those used by \fBbackward\-word\fP.
-.TP
-.B unix\-word\-rubout (C\-w)
-Kill the word behind the cursor, using white space as a word boundary.
-The word boundaries are different from
-.BR backward\-kill\-word .
-.TP
-.B delete\-horizontal\-space (M\-\e)
-Delete all spaces and tabs around point.
-.TP
-.B kill\-region
-Kill the text between the point and \fImark\fP (saved cursor position).

-.TP
-.B yank\-pop (M\-y)
-Rotate the kill ring, and yank the new top. Only works following
-.B yank
-or
-.BR yank\-pop .
-.PD
-.SS Numeric Arguments
-.PP
-.PD 0
-.TP
-.B digit\-argument (M\-0, M\-1, ..., M\-\-)
-Add this digit to the argument already accumulating, or start a new
-argument. M\-\- starts a negative argument.
-.TP
-.B universal\-argument
-This is another way to specify an argument.
-If this command is followed by one or more digits, optionally with a
-leading minus sign, those digits define the argument.
-If the command is followed by digits, executing
-.B universal\-argument
-again ends the numeric argument, but is otherwise ignored.
-As a special case, if this command is immediately followed by a
-character that is neither a digit or minus sign, the argument count
-for the next command is multiplied by four.
-The argument count is initially one, so executing this function the
-first time makes the argument count four, a second time makes the
-argument count sixteen, and so on.
-.PD
-.SS Completing
-.PP
-.PD 0
-.TP
-.B complete (TAB)
-Attempt to perform completion on the text before point.
-The actual completion performed is application-specific.
-.BR Bash ,
-for instance, attempts completion treating the text as a variable
-(if the text begins with \fB$\fP), username (if the text begins with
-\fB~\fP), hostname (if the text begins with \fB@\fP), or
-command (including aliases and functions) in turn. If none
-of these produces a match, filename completion is attempted.
-.BR Gdb ,
-on the other hand,
-allows completion of program functions and variables, and
-only attempts filename completion under certain circumstances.
-.TP
-.B possible\-completions (M\-?)
-List the possible completions of the text before point.

-The following is a list of the default emacs and vi bindings.
-Characters with the 8th bit set are written as M\-<character>, and
-are referred to as
-.I metafied
-characters.
-The printable ASCII characters not mentioned in the list of emacs
-standard bindings are bound to the
-.I self\-insert
-function, which just inserts the given character into the input line.
-In vi insertion mode, all characters not specifically mentioned are
-bound to
-.IR self\-insert .
-Characters assigned to signal generation by
-.IR stty (1)
-or the terminal driver, such as C-Z or C-C,
-retain that function.
-Upper and lower case
-.I metafied
-characters are bound to the same function in the emacs mode
-meta keymap.
-The remaining characters are unbound, which causes readline
-to ring the bell (subject to the setting of the
-.B bell\-style
-variable).

-.Sh NAME
-.Nm telnet
-.Nd user interface to the
-.Tn TELNET
-protocol
-.Sh SYNOPSIS
-.Nm telnet
-.Op Fl 8EFKLacdfrx
-.Op Fl S Ar tos
-.Op Fl X Ar authtype
-.Op Fl e Ar escapechar
-.Op Fl k Ar realm
-.Op Fl l Ar user
-.Op Fl n Ar tracefile

-.Sh DESCRIPTION
-The
-.Nm telnet
-command
-is used to communicate with another host using the
-.Tn TELNET
-protocol.
-If
-.Nm telnet
-is invoked without the
-.Ar host
-argument, it enters command mode,
-indicated by its prompt
-.Pq Nm telnet\&> .
-In this mode, it accepts and executes the commands listed below.
-If it is invoked with arguments, it performs an
-.Ic open
-command with those arguments.
-.Pp
-Options:
-.Bl -tag -width indent
-.It Fl 8
-Specifies an 8-bit data path. This causes an attempt to
-negotiate the
-.Dv TELNET BINARY
-option on both input and output.
-.It Fl E
-Stops any character from being recognized as an escape character.
-.It Fl F
-If Kerberos V5 authentication is being used, the
-.Fl F
-option allows the local credentials to be forwarded
-to the remote system, including any credentials that
-have already been forwarded into the local environment.
-.It Fl K
-Specifies no automatic login to the remote system.
-.It Fl L
-Specifies an 8-bit data path on output. This causes the
-BINARY option to be negotiated on output.
-.It Fl S Ar tos
-Sets the IP type-of-service (TOS) option for the telnet
-connection to the value
-.Ar tos,
-which can be a numeric TOS value
-or, on systems that support it, a symbolic
-TOS name found in the /etc/iptos file.
-.It Fl X Ar atype
-Disables the
-.Ar atype
-type of authentication.
-.It Fl a
-Attempt automatic login.
-Currently, this sends the user name via the
-.Ev USER
-variable
-of the
-.Ev ENVIRON
-option if supported by the remote system.
-The name used is that of the current user as returned by
-.Xr getlogin 2
-if it agrees with the current user ID,
-otherwise it is the name associated with the user ID.
-.It Fl c
-Disables the reading of the user's
-.Pa \&.telnetrc
-file. (See the
-.Ic toggle skiprc
-command on this man page.)
-.It Fl d
-Sets the initial value of the
-.Ic debug
-toggle to
-.Dv TRUE
-.It Fl e Ar escape char
-Sets the initial
-.Nm
-.Nm telnet
-escape character to
-.Ar escape char.
-If
-.Ar escape char
-is omitted, then
-there will be no escape character.
-.It Fl f
-If Kerberos V5 authentication is being used, the
-.Fl f
-option allows the local credentials to be forwarded to the remote system.
-.ne 1i
-.It Fl k Ar realm
-If Kerberos authentication is being used, the
-.Fl k
-option requests that telnet obtain tickets for the remote host in
-realm realm instead of the remote host's realm, as determined
-by
-.Xr krb_realmofhost 3 .
-.It Fl l Ar user
-When connecting to the remote system, if the remote system
-understands the
-.Ev ENVIRON
-option, then
-.Ar user
-will be sent to the remote system as the value for the variable USER.
-This option implies the
-.Fl a
-option.
-This option may also be used with the
-.Ic open
-command.
-.It Fl n Ar tracefile
-Opens
-.Ar tracefile
-for recording trace information.
-See the
-.Ic set tracefile
-command below.
-.It Fl r
-Specifies a user interface similar to
-.Xr rlogin 1 .
-In this
-mode, the escape character is set to the tilde (~) character,
-unless modified by the -e option.
-.It Fl x
-Turns on encryption of the data stream if possible. This
-option is not available outside of the United States and
-Canada.
-.It Ar host
-Indicates the official name, an alias, or the Internet address
-of a remote host.
-.It Ar port
-Indicates a port number (address of an application). If a number is
-not specified, the default
-.Nm telnet
-port is used.
-.El
-.Pp
-When in rlogin mode, a line of the form ~. disconnects from the
-remote host; ~ is the telnet escape character.
-Similarly, the line ~^Z suspends the telnet session.
-The line ~^] escapes to the normal telnet escape prompt.
-.Pp
-Once a connection has been opened,
-.Nm telnet
-will attempt to enable the
-.Dv TELNET LINEMODE
-option.
-If this fails, then
-.Nm telnet
-will revert to one of two input modes:
-either \*(Lqcharacter at a time\*(Rq
-or \*(Lqold line by line\*(Rq
-depending on what the remote system supports.
-.Pp
-When
-.Dv LINEMODE
-is enabled, character processing is done on the
-local system, under the control of the remote system. When input
-editing or character echoing is to be disabled, the remote system
-will relay that information. The remote system will also relay
-changes to any special characters that happen on the remote
-system, so that they can take effect on the local system.
-.Pp
-In \*(Lqcharacter at a time\*(Rq mode, most
-text typed is immediately sent to the remote host for processing.
-.Pp
-In \*(Lqold line by line\*(Rq mode, all text is echoed locally,
-and (normally) only completed lines are sent to the remote host.
-The \*(Lqlocal echo character\*(Rq (initially \*(Lq^E\*(Rq) may be used
-to turn off and on the local echo
-(this would mostly be used to enter passwords
-without the password being echoed).
-.Pp
-If the
-.Dv LINEMODE
-option is enabled, or if the
-.Ic localchars
-toggle is
-.Dv TRUE
-(the default for \*(Lqold line by line\*(Lq; see below),
-the user's
-.Ic quit ,
-.Ic intr ,
-and
-.Ic flush
-characters are trapped locally, and sent as
-.Tn TELNET
-protocol sequences to the remote side.
-If
-.Dv LINEMODE
-has ever been enabled, then the user's
-.Ic susp
-and
-.Ic eof
-are also sent as
-.Tn TELNET
-protocol sequences,
-and
-.Ic quit
-is sent as a
-.Dv TELNET ABORT
-instead of
-.Dv BREAK
-There are options (see
-.Ic toggle
-.Ic autoflush
-and
-.Ic toggle
-.Ic autosynch
-below)
-which cause this action to flush subsequent output to the terminal
-(until the remote host acknowledges the
-.Tn TELNET
-sequence) and flush previous terminal input
-(in the case of
-.Ic quit
-and
-.Ic intr ) .
-.Pp
-While connected to a remote host,
-.Nm telnet
-command mode may be entered by typing the
-.Nm telnet
-\*(Lqescape character\*(Rq (initially \*(Lq^]\*(Rq).
-When in command mode, the normal terminal editing conventions are available.
-.Pp
-The following
-.Nm telnet
-commands are available.
-Only enough of each command to uniquely identify it need be typed
-(this is also true for arguments to the
-.Ic mode ,
-.Ic set ,
-.Ic toggle ,
-.Ic unset ,
-.Ic slc ,
-.Ic environ ,
-and
-.Ic display
-commands).
-.Pp
-.Bl -tag -width "mode type"
-.It Ic auth Ar argument ...
-The auth command manipulates the information sent through the
-.Dv TELNET AUTHENTICATE
-option. Valid arguments for the
-auth command are as follows:
-.Bl -tag -width "disable type"
-.It Ic disable Ar type
-Disables the specified type of authentication. To
-obtain a list of available types, use the
-.Ic auth disable \&?
-command.
-.It Ic enable Ar type
-Enables the specified type of authentication. To
-obtain a list of available types, use the
-.Ic auth enable \&?
-command.
-.It Ic status
-Lists the current status of the various types of
-authentication.
-.El
-.It Ic close
-Close a
-.Tn TELNET
-session and return to command mode.
-.It Ic display Ar argument ...
-Displays all, or some, of the
-.Ic set
-and
-.Ic toggle
-values (see below).
-.It Ic encrypt Ar argument ...
-The encrypt command manipulates the information sent through the
-.Dv TELNET ENCRYPT
-option.
-.Pp
-Note: Because of export controls, the
-.Dv TELNET ENCRYPT
-option is not supported outside of the United States and Canada.
-.Pp
-Valid arguments for the encrypt command are as follows:
-.Bl -tag -width Ar
-.It Ic disable Ar type Ic [input|output]
-Disables the specified type of encryption. If you
-omit the input and output, both input and output
-are disabled. To obtain a list of available
-types, use the
-.Ic encrypt disable \&?
-command.
-.It Ic enable Ar type Ic [input|output]
-Enables the specified type of encryption. If you
-omit input and output, both input and output are
-enabled. To obtain a list of available types, use the
-.Ic encrypt enable \&?
-command.
-.It Ic input
-This is the same as the
-.Ic encrypt start input
-command.
-.It Ic -input
-This is the same as the
-.Ic encrypt stop input
-command.
-.It Ic output
-This is the same as the
-.Ic encrypt start output
-command.
-.It Ic -output
-This is the same as the
-.Ic encrypt stop output
-command.
-.It Ic start Ic [input|output]
-Attempts to start encryption. If you omit
-.Ic input
-and
-.Ic output,
-both input and output are enabled. To
-obtain a list of available types, use the
-.Ic encrypt enable \&?
-command.
-.It Ic status
-Lists the current status of encryption.
-.It Ic stop Ic [input|output]
-Stops encryption. If you omit input and output,
-encryption is on both input and output.
-.It Ic type Ar type
-Sets the default type of encryption to be used
-with later
-.Ic encrypt start
-or
-.Ic encrypt stop
-commands.
-.El
-.It Ic environ Ar arguments...
-The
-.Ic environ
-command is used to manipulate the
-the variables that my be sent through the
-.Dv TELNET ENVIRON
-option.
-The initial set of variables is taken from the users
-environment, with only the
-.Ev DISPLAY
-and
-.Ev PRINTER
-variables being exported by default.
-The
-.Ev USER
-variable is also exported if the
-.Fl a
-or
-.Fl l
-options are used.
-.br
-Valid arguments for the
-.Ic environ
-command are:
-.Bl -tag -width Fl
-.It Ic define Ar variable value
-Define the variable
-.Ar variable
-to have a value of
-.Ar value.
-Any variables defined by this command are automatically exported.
-The
-.Ar value
-may be enclosed in single or double quotes so
-that tabs and spaces may be included.
-.It Ic undefine Ar variable

-other variables will only be sent if explicitly requested.
-.It Ic \&?
-Prints out help information for the
-.Ic environ
-command.
-.El
-.It Ic logout
-Sends the
-.Dv TELNET LOGOUT
-option to the remote side.
-This command is similar to a
-.Ic close
-command; however, if the remote side does not support the
-.Dv LOGOUT
-option, nothing happens.
-If, however, the remote side does support the
-.Dv LOGOUT
-option, this command should cause the remote side to close the
-.Tn TELNET
-connection.
-If the remote side also supports the concept of
-suspending a user's session for later reattachment,
-the logout argument indicates that you
-should terminate the session immediately.
-.It Ic mode Ar type
-.Ar Type
-is one of several options, depending on the state of the
-.Tn TELNET
-session.
-The remote host is asked for permission to go into the requested mode.
-If the remote host is capable of entering that mode, the requested
-mode will be entered.
-.Bl -tag -width Ar
-.It Ic character

-This requires that the
-.Dv LINEMODE
-option be enabled.
-.It Ic edit Pq Ic \-edit
-Attempt to enable (disable) the
-.Dv EDIT
-mode of the
-.Dv LINEMODE
-option.
-This requires that the
-.Dv LINEMODE
-option be enabled.
-.It Ic softtabs Pq Ic \-softtabs
-Attempt to enable (disable) the
-.Dv SOFT_TAB
-mode of the
-.Dv LINEMODE
-option.
-This requires that the
-.Dv LINEMODE
-option be enabled.
-.ne 1i
-.It Ic litecho Pq Ic \-litecho
-Attempt to enable (disable) the
-.Dv LIT_ECHO
-mode of the
-.Dv LINEMODE
-option.
-This requires that the
-.Dv LINEMODE
-option be enabled.
-.It Ic \&?
-Prints out help information for the
-.Ic mode
-command.
-.El
-.It Xo
-.Ic open Ar host
-.Oo Op Fl l
-.Ar user
-.Oc Ns Oo Fl
-.Ar port Oc
-.Xc
-Open a connection to the named host.
-If no port number
-is specified,
-.Nm telnet
-will attempt to contact a
-.Tn TELNET
-server at the default port.
-The host specification may be either a host name (see
-.Xr hosts 5 )
-or an Internet address specified in the \*(Lqdot notation\*(Rq (see
-.Xr inet 3 ) .
-The
-.Op Fl l
-option may be used to specify the user name
-to be passed to the remote system via the
-.Ev ENVIRON
-option.
-When connecting to a non-standard port,
-.Nm telnet
-omits any automatic initiation of
-.Tn TELNET
-options. When the port number is preceded by a minus sign,
-the initial option negotiation is done.
-After establishing a connection, the file
-.Pa \&.telnetrc
-in the
-users home directory is opened. Lines beginning with a # are
-comment lines. Blank lines are ignored. Lines that begin
-without white space are the start of a machine entry. The
-first thing on the line is the name of the machine that is
-being connected to. The rest of the line, and successive
-lines that begin with white space are assumed to be
-.Nm telnet
-commands and are processed as if they had been typed
-in manually to the
-.Nm telnet
-command prompt.
-.It Ic quit
-Close any open
-.Tn TELNET
-session and exit
-.Nm telnet .
-An end of file (in command mode) will also close a session and exit.
-.It Ic send Ar arguments
-Sends one or more special character sequences to the remote host.
-The following are the arguments which may be specified
-(more than one argument may be specified at a time):
-.Pp
-.Bl -tag -width escape
-.It Ic abort
-Sends the
-.Dv TELNET ABORT
-(Abort
-processes)
-sequence.
-.It Ic ao
-Sends the
-.Dv TELNET AO
-(Abort Output) sequence, which should cause the remote system to flush
-all output
-.Em from
-the remote system
-.Em to
-the user's terminal.
-.It Ic ayt
-Sends the
-.Dv TELNET AYT
-(Are You There)
-sequence, to which the remote system may or may not choose to respond.
-.It Ic brk
-Sends the
-.Dv TELNET BRK
-(Break) sequence, which may have significance to the remote
-system.
-.It Ic ec
-Sends the
-.Dv TELNET EC
-(Erase Character)
-sequence, which should cause the remote system to erase the last character
-entered.
-.It Ic el
-Sends the
-.Dv TELNET EL
-(Erase Line)
-sequence, which should cause the remote system to erase the line currently
-being entered.
-.It Ic eof
-Sends the
-.Dv TELNET EOF
-(End Of File)
-sequence.
-.It Ic eor
-Sends the
-.Dv TELNET EOR
-(End of Record)
-sequence.
-.It Ic escape
-Sends the current
-.Nm telnet
-escape character (initially \*(Lq^\*(Rq).

-Sends the
-.Dv TELNET GA
-(Go Ahead)
-sequence, which likely has no significance to the remote system.
-.It Ic getstatus
-If the remote side supports the
-.Dv TELNET STATUS
-command,
-.Ic getstatus
-will send the subnegotiation to request that the server send
-its current option status.
-.ne 1i

-.Ic localchars
-are both
-.Dv TRUE ,
-then when the
-.Ic ao ,
-or
-.Ic quit
-characters are recognized (and transformed into
-.Tn TELNET
-sequences; see
-.Ic set
-above for details),
-.Nm telnet
-refuses to display any data on the user's terminal
-until the remote system acknowledges (via a
-.Dv TELNET TIMING MARK
-option)
-that it has processed those
-.Tn TELNET
-sequences.
-The initial value for this toggle is
-.Dv TRUE
-if the terminal user had not
-done an "stty noflsh", otherwise
-.Dv FALSE
-(see
-.Xr stty 1 ) .
-.It Ic autodecrypt
-When the
-.Dv TELNET ENCRYPT
-option is negotiated, by
-default the actual encryption (decryption) of the data
-stream does not start automatically. The autoencrypt
-(autodecrypt) command states that encryption of the
-output (input) stream should be enabled as soon as
-possible.
-.sp
-.Pp
-Note: Because of export controls, the
-.Dv TELNET ENCRYPT
-option is not supported outside the United States and Canada.
-.It Ic autologin
-If the remote side supports the
-.Dv TELNET AUTHENTICATION
-option
-.Tn TELNET
-attempts to use it to perform automatic authentication. If the
-.Dv AUTHENTICATION
-option is not supported, the user's login
-name are propagated through the
-.Dv TELNET ENVIRON
-option.
-This command is the same as specifying
-.Ar a
-option on the
-.Ic open
-command.
-.It Ic autosynch
-If
-.Ic autosynch
-and
-.Ic localchars
-are both
-.Dv TRUE ,
-then when either the
-.Ic intr
-or
-.Ic quit

-above for descriptions of the
-.Ic intr
-and
-.Ic quit
-characters), the resulting
-.Tn TELNET
-sequence sent is followed by the

-If this is
-.Dv FALSE ,
-then carriage returns will be send as
-.Li <CR><NUL> .
-The initial value for this toggle is
-.Dv FALSE .
-.It Ic crmod
-Toggle carriage return mode.
-When this mode is enabled, most carriage return characters received from
-the remote host will be mapped into a carriage return followed by
-a line feed.
-This mode does not affect those characters typed by the user, only
-those received from the remote host.
-This mode is not very useful unless the remote host
-only sends carriage return, but never line feed.
-The initial value for this toggle is
-.Dv FALSE .
-.It Ic debug
-Toggles socket level debugging (useful only to the
-.Ic super user ) .
-The initial value for this toggle is
-.Dv FALSE .
-.It Ic encdebug
-Turns on debugging information for the encryption code.
-.It Ic localchars
-If this is
-.Dv TRUE ,
-then the
-.Ic flush ,
-.Ic interrupt ,
-.Ic quit ,
-.Ic erase ,
-and
-.Ic kill
-characters (see
-.Ic set
-above) are recognized locally, and transformed into (hopefully) appropriate
-.Tn TELNET
-control sequences
-(respectively
-.Ic ao ,
-.Ic ip ,
-.Ic brk ,
-.Ic ec ,
-and
-.Ic el ;
-see
-.Ic send
-above).
-The initial value for this toggle is
-.Dv TRUE
-in \*(Lqold line by line\*(Rq mode,
-and
-.Dv FALSE
-in \*(Lqcharacter at a time\*(Rq mode.
-When the
-.Dv LINEMODE
-option is enabled, the value of
-.Ic localchars
-is ignored, and assumed to always be
-.Dv TRUE .
-If
-.Dv LINEMODE
-has ever been enabled, then
-.Ic quit
-is sent as
-.Ic abort ,
-and
-.Ic eof and
-.B suspend
-are sent as
-.Ic eof and
-.Ic susp ,
-see
-.Ic send
-above).
-.It Ic netdata
-Toggles the display of all network data (in hexadecimal format).
-The initial value for this toggle is
-.Dv FALSE .

-command will be formatted in a more user readable format.
-Spaces are put between each character in the output, and the
-beginning of any
-.Tn TELNET
-escape sequence is preceded by a '*' to aid in locating them.
-.It Ic skiprc
-When the skiprc toggle is
-.Dv TRUE ,
-.Tn TELNET
-skips the reading of the
-.Pa \&.telnetrc
-file in the users home
-directory when connections are opened. The initial
-value for this toggle is
-.Dv FALSE.
-.It Ic termdata
-Toggles the display of all terminal data (in hexadecimal format).
-The initial value for this toggle is
-.Dv FALSE .
-.It Ic verbose_encrypt
-When the
-.Ic verbose_encrypt
-toggle is
-.Dv TRUE ,
-.Tn TELNET
-prints out a message each time encryption is enabled or
-disabled. The initial value for this toggle is

- * The will/wont/do/dont state machines are based on Dave Borman's
- * Telnet option processing state machine.
- *
- * These correspond to the following states:
- * my_state = the last negotiated state
- * want_state = what I want the state to go to
- * want_resp = how many requests I have sent
- * All state defaults are negative, and resp defaults to 0.
- *
- * When initiating a request to change state to new_state:
- *
- * if ((want_resp == 0 && new_state == my_state) || want_state == new_state) {
- * do nothing;
- * } else {
- * want_state = new_state;
- * send new_state;
- * want_resp++;
- * }
- *
- * When receiving new_state:
- *
- * if (want_resp) {
- * want_resp--;
- * if (want_resp && (new_state == my_state))
- * want_resp--;
- * }
- * if ((want_resp == 0) && (new_state != want_state)) {
- * if (ok_to_switch_to new_state)
- * want_state = new_state;
- * else
- * want_resp++;
- * send want_state;
- * }
- * my_state = new_state;
- *
- * Note that new_state is implied in these functions by the function itself.
- * will and do imply positive new_state, wont and dont imply negative.
- *
- * Finally, there is one catch. If we send a negative response to a
- * positive request, my_state will be the positive while want_state will
- * remain negative. my_state will revert to negative when the negative
- * acknowlegment arrives from the peer. Thus, my_state generally tells
- * us not only the last negotiated state, but also tells us what the peer
- * wants to be doing as well. It is important to understand this difference
- * as we may wish to be processing data streams based on our desired state
- * (want_state) or based on what the peer thinks the state is (my_state).
- *
- * This all works fine because if the peer sends a positive request, the data
- * that we receive prior to negative acknowlegment will probably be affected
- * by the positive state, and we can process it as such (if we can; if we
- * can't then it really doesn't matter). If it is that important, then the
- * peer probably should be buffering until this option state negotiation
- * is complete.

-.Sh NAME
-.Nm telnetd
-.Nd DARPA
-.Tn TELNET
-protocol server
-.Sh SYNOPSIS
-.Nm /usr/libexec/telnetd
-.Op Fl BUhlkns
-.Op Fl D Ar debugmode
-.Op Fl I Ns Ar initid
-.Op Fl S Ar tos
-.Op Fl X Ar authtype
-.Op Fl a Ar authmode
-.Op Fl edebug
-.Op Fl p Ar loginprog
-.Op Fl r Ns Ar lowpty-highpty
-.Op Fl u Ar len
-.Op Fl debug Op Ar port
-.Sh DESCRIPTION
-The
-.Nm
-command is a server which supports the
-.Tn DARPA
-standard
-.Tn TELNET
-virtual terminal protocol.
-.Nm Telnetd
-is normally invoked by the internet server (see
-.Xr inetd 8 )
-for requests to connect to the
-.Tn TELNET
-port as indicated by the
-.Pa /etc/services
-file (see
-.Xr services 5 ).
-The
-.Fl debug
-option may be used to start up
-.Nm
-manually, instead of through
-.Xr inetd 8 .
-If started up this way,
-.Ar port
-may be specified to run
-.Nm
-on an alternate
-.Tn TCP
-port number.
-.Pp
-The
-.Nm
-command accepts the following options:
-.Bl -tag -width indent
-.It Fl a Ar authmode
-This option may be used for specifying what mode should
-be used for authentication.
-Note that this option is only useful if
-.Nm
-has been compiled with support for the
-.Dv AUTHENTICATION
-option.
-There are several valid values for
-.Ar authmode :
-.Bl -tag -width debug
-.It Cm debug
-Turn on authentication debugging code.
-.It Cm user
-Only allow connections when the remote user
-can provide valid authentication information
-to identify the remote user,
-and is allowed access to the specified account
-without providing a password.
-.It Cm valid
-Only allow connections when the remote user
-can provide valid authentication information
-to identify the remote user.
-The
-.Xr login 1
-command will provide any additional user verification
-needed if the remote user is not allowed automatic
-access to the specified account.
-.It Cm other
-Only allow connections that supply some authentication information.
-This option is currently not supported
-by any of the existing authentication mechanisms,
-and is thus the same as specifying
-.Fl a
-.Cm valid .
-.It Cm none
-This is the default state.
-Authentication information is not required.
-If no or insufficient authentication information
-is provided, then the
-.Xr login 1
-program will provide the necessary user
-verification.
-.It Cm off
-Disable the authentication code.
-All user verification will happen through the
-.Xr login 1
-program.
-.El
-.It Fl B
-Specify bftp server mode. In this mode,
-.Nm
-causes login to start a
-.Xr bftp 1
-session rather than the user's
-normal shell. In bftp daemon mode normal
-logins are not supported, and it must be used
-on a port other than the normal
-.Tn TELNET
-port.
-.It Fl D Ar debugmode
-This option may be used for debugging purposes.
-This allows
-.Nm
-to print out debugging information
-to the connection, allowing the user to see what
-.Nm
-is doing.
-There are several possible values for
-.Ar debugmode :
-.Bl -tag -width exercise
-.It Cm options
-Print information about the negotiation of
-.Tn TELNET
-options.
-.It Cm report
-Print the
-.Cm options
-information, plus some additional information
-about what processing is going on.
-.It Cm netdata
-Display the data stream received by
-.Nm Ns .
-.It Cm ptydata
-Display data written to the pty.
-.It Cm exercise
-Has not been implemented yet.
-.El
-.It Fl debug
-Enable debugging on each socket created by
-.Nm
-(see
-.Dv SO_DEBUG
-in
-.Xr socket 2 ) .
-.It Fl edebug
-If
-.Nm
-has been compiled with support for data encryption, then the
-.Fl edebug
-option may be used to enable encryption debugging code.
-.It Fl p Ar loginprog
-Specify an alternate
-.Xr login 1
-command to run to complete the login. The alternate command must
-understand the same command arguments as the standard login.
-.It Fl h
-Disable the printing of host-specific information before
-login has been completed.
-.It Fl I Ar initid
-This option is only applicable to
-.Tn UNICOS
-systems prior to 7.0.
-It specifies the
-.Dv ID
-from
-.Pa /etc/inittab
-to use when init starts login sessions. The default
-.Dv ID
-is
-.Dv fe.
-.It Fl k
-This option is only useful if
-.Nm
-has been compiled with both linemode and kludge linemode
-support. If the
-.Fl k
-option is specified, then if the remote client does not
-support the
-.Dv LINEMODE
-option, then
-.Nm
-will operate in character at a time mode.
-It will still support kludge linemode, but will only
-go into kludge linemode if the remote client requests
-it.
-(This is done by the client sending
-.Dv DONT SUPPRESS-GO-AHEAD
-and
-.Dv DONT ECHO . )
-The
-.Fl k
-option is most useful when there are remote clients
-that do not support kludge linemode, but pass the heuristic
-(if they respond with
-.Dv WILL TIMING-MARK
-in response to a
-.Dv DO TIMING-MARK)
-for kludge linemode support.
-.It Fl l
-Specify line mode. Try to force clients to use line-
-at-a-time mode.
-If the
-.Dv LINEMODE
-option is not supported, it will go
-into kludge linemode.
-.It Fl n
-Disable
-.Dv TCP
-keep-alives. Normally
-.Nm
-enables the
-.Tn TCP
-keep-alive mechanism to probe connections that
-have been idle for some period of time to determine
-if the client is still there, so that idle connections
-from machines that have crashed or can no longer
-be reached may be cleaned up.
-.It Fl r Ar lowpty-highpty
-This option is only enabled when
-.Nm
-is compiled for
-.Dv UNICOS.
-It specifies an inclusive range of pseudo-terminal devices to
-use. If the system has sysconf variable
-.Dv _SC_CRAY_NPTY
-configured, the default pty search range is 0 to
-.Dv _SC_CRAY_NPTY;
-otherwise, the default range is 0 to 128. Either
-.Ar lowpty
-or
-.Ar highpty
-may be omitted to allow changing
-either end of the search range. If
-.Ar lowpty
-is omitted, the - character is still required so that
-.Nm
-can differentiate
-.Ar highpty
-from
-.Ar lowpty .
-.It Fl s
-This option is only enabled if
-.Nm
-is compiled with support for
-.Tn SecurID
-cards.
-It causes the
-.Fl s
-option to be passed on to
-.Xr login 1 ,
-and thus is only useful if
-.Xr login 1
-supports the
-.Fl s
-flag to indicate that only
-.Tn SecurID
-validated logins are allowed, and is
-usually useful for controlling remote logins
-from outside of a firewall.
-.It Fl S Ar tos
-.It Fl u Ar len
-This option is used to specify the size of the field
-in the
-.Dv utmp
-structure that holds the remote host name.
-If the resolved host name is longer than
-.Ar len ,
-the dotted decimal value will be used instead.
-This allows hosts with very long host names that
-overflow this field to still be uniquely identified.
-Specifying
-.Fl u0
-indicates that only dotted decimal addresses
-should be put into the
-.Pa utmp
-file.
-.ne 1i
-.It Fl U
-This option causes
-.Nm
-to refuse connections from addresses that
-cannot be mapped back into a symbolic name
-via the
-.Xr gethostbyaddr 3
-routine.
-.It Fl X Ar authtype
-This option is only valid if
-.Nm
-has been built with support for the authentication option.
-It disables the use of
-.Ar authtype
-authentication, and
-can be used to temporarily disable
-a specific authentication type without having to recompile
-.Nm Ns .
-.El
-.Pp
-.Nm Telnetd
-operates by allocating a pseudo-terminal device (see
-.Xr pty 4 )
-for a client, then creating a login process which has
-the slave side of the pseudo-terminal as
-.Dv stdin ,
-.Dv stdout
-and
-.Dv stderr .
-.Nm Telnetd
-manipulates the master side of the pseudo-terminal,
-implementing the
-.Tn TELNET
-protocol and passing characters
-between the remote client and the login process.
-.Pp
-When a
-.Tn TELNET
-session is started up,
-.Nm
-sends
-.Tn TELNET
-options to the client side indicating
-a willingness to do the
-following
-.Tn TELNET
-options, which are described in more detail below:
-.Bd -literal -offset indent
-DO AUTHENTICATION
-WILL ENCRYPT
-DO TERMINAL TYPE
-DO TSPEED
-DO XDISPLOC
-DO NEW-ENVIRON
-DO ENVIRON
-WILL SUPPRESS GO AHEAD
-DO ECHO
-DO LINEMODE
-DO NAWS
-WILL STATUS
-DO LFLOW
-DO TIMING-MARK
-.Ed
-.Pp
-The pseudo-terminal allocated to the client is configured
-to operate in \*(lqcooked\*(rq mode, and with
-.Dv XTABS and
-.Dv CRMOD
-enabled (see
-.Xr tty 4 ) .
-.Pp
-.Nm Telnetd
-has support for enabling locally the following
-.Tn TELNET
-options:
-.Bl -tag -width "DO AUTHENTICATION"
-.It "WILL ECHO"
-When the
-.Dv LINEMODE
-option is enabled, a
-.Dv WILL ECHO
-or
-.Dv WONT ECHO
-will be sent to the client to indicate the
-current state of terminal echoing.
-When terminal echo is not desired, a
-.Dv WILL ECHO
-is sent to indicate that
-.Nm
-will take care of echoing any data that needs to be
-echoed to the terminal, and then nothing is echoed.
-When terminal echo is desired, a
-.Dv WONT ECHO
-is sent to indicate that
-.Nm
-will not be doing any terminal echoing, so the
-client should do any terminal echoing that is needed.
-.It "WILL BINARY"
-Indicate that the client is willing to send a
-8 bits of data, rather than the normal 7 bits
-of the Network Virtual Terminal.
-.It "WILL SGA"
-Indicate that it will not be sending
-.Dv IAC GA,
-go ahead, commands.
-.It "WILL STATUS"
-Indicate a willingness to send the client, upon
-request, of the current status of all
-.Tn TELNET
-options.
-.It "WILL TIMING-MARK"
-Whenever a

-command is received, it is always responded
-to with a
-.Dv WILL TIMING-MARK
-.ne 1i
-.It "WILL LOGOUT"
-When a
-.Dv DO LOGOUT
-is received, a
-.Dv WILL LOGOUT
-is sent in response, and the
-.Tn TELNET
-session is shut down.
-.It "WILL ENCRYPT"
-Only sent if
-.Nm
-is compiled with support for data encryption, and
-indicates a willingness to decrypt
-the data stream.
-.El
-.Pp
-.Nm Telnetd
-has support for enabling remotely the following
-.Tn TELNET
-options:
-.Bl -tag -width "DO AUTHENTICATION"
-.It "DO BINARY"
-Sent to indicate that
-.Nm
-is willing to receive an 8 bit data stream.
-.It "DO LFLOW"
-Requests that the client handle flow control
-characters remotely.
-.It "DO ECHO"
-This is not really supported, but is sent to identify a 4.2BSD
-.Xr telnet 1
-client, which will improperly respond with
-.Dv WILL ECHO.
-If a
-.Dv WILL ECHO
-is received, a
-.Dv DONT ECHO
-will be sent in response.
-.It "DO TERMINAL-TYPE"
-Indicate a desire to be able to request the
-name of the type of terminal that is attached
-to the client side of the connection.
-.It "DO SGA"
-Indicate that it does not need to receive

-.Nm
-is compiled with support for both linemode and
-kludge linemode, and the client responded with
-.Dv WONT LINEMODE.
-If the client responds with
-.Dv WILL TM,
-the it is assumed that the client supports
-kludge linemode.
-Note that the
-.Op Fl k
-option can be used to disable this.
-.It "DO AUTHENTICATION"
-Only sent if
-.Nm
-is compiled with support for authentication, and
-indicates a willingness to receive authentication
-information for automatic login.
-.It "DO ENCRYPT"
-Only sent if

- * localstat
- *
- * This function handles all management of linemode.
- *
- * Linemode allows the client to do the local editing of data
- * and send only complete lines to the server. Linemode state is
- * based on the state of the pty driver. If the pty is set for
- * external processing, then we can use linemode. Further, if we
- * can use real linemode, then we can look at the edit control bits
- * in the pty to determine what editing the client should do.
- *
- * Linemode support uses the following state flags to keep track of
- * current and desired linemode state.
- * alwayslinemode : true if -l was specified on the telnetd
- * command line. It means to have linemode on as much as
- * possible.
- *
- * lmodetype: signifies whether the client can
- * handle real linemode, or if use of kludgeomatic linemode
- * is preferred. It will be set to one of the following:
- * REAL_LINEMODE : use linemode option
- * NO_KLUDGE : don't initiate kludge linemode.
- * KLUDGE_LINEMODE : use kludge linemode
- * NO_LINEMODE : client is ignorant of linemode
- *
- * linemode, uselinemode : linemode is true if linemode
- * is currently on, uselinemode is the state that we wish
- * to be in. If another function wishes to turn linemode
- * on or off, it sets or clears uselinemode.
- *
- * editmode, useeditmode : like linemode/uselinemode, but
- * these contain the edit mode states (edit and trapsig).
- *
- * The state variables correspond to some of the state information
- * in the pty.
- * linemode:
- * In real linemode, this corresponds to whether the pty
- * expects external processing of incoming data.
- * In kludge linemode, this more closely corresponds to the
- * whether normal processing is on or not. (ICANON in
- * system V, or COOKED mode in BSD.)
- * If the -l option was specified (alwayslinemode), then
- * an attempt is made to force external processing on at
- * all times.
- *
- * The following heuristics are applied to determine linemode
- * handling within the server.
- * 1) Early on in starting up the server, an attempt is made
- * to negotiate the linemode option. If this succeeds
- * then lmodetype is set to REAL_LINEMODE and all linemode
- * processing occurs in the context of the linemode option.
- * 2) If the attempt to negotiate the linemode option failed,
- * and the "-k" (don't initiate kludge linemode) isn't set,
- * then we try to use kludge linemode. We test for this
- * capability by sending "do Timing Mark". If a positive
- * response comes back, then we assume that the client
- * understands kludge linemode (ech!) and the
- * lmodetype flag is set to KLUDGE_LINEMODE.
- * 3) Otherwise, linemode is not supported at all and
- * lmodetype remains set to NO_LINEMODE (which happens
- * to be 0 for convenience).
- * 4) At any time a command arrives that implies a higher
- * state of linemode support in the client, we move to that
- * linemode support.
- *
- * A short explanation of kludge linemode is in order here.
- * 1) The heuristic to determine support for kludge linemode
- * is to send a do timing mark. We assume that a client
- * that supports timing marks also supports kludge linemode.
- * A risky proposition at best.
- * 2) Further negotiation of linemode is done by changing the
- * the server's state regarding SGA. If server will SGA,
- * then linemode is off, if server won't SGA, then linemode
- * is on.
