-.Dt NG_TTY 4
-.Os FreeBSD
-.Sh NAME
-.Nm ng_tty
-.Nd netgraph node type that is also a line discipline
-.Sh SYNOPSIS
-.Fd #include <sys/ttycom.h>
-.Fd #include <netgraph/ng_message.h>
-.Fd #include <netgraph/ng_tty.h>
-.Sh DESCRIPTION
-The
-.Nm tty
-node type is both a netgraph node type and a line discipline.
-A new node is created when the corresponding line discipline,
-.Dv NETGRAPHDISC ,
-is registered on a tty device (see
-.Xr tty 4 ) .
-.Pp
-The node has a single hook called
-.Dv hook .
-Incoming bytes received on the tty device are sent out on this hook,
-and frames received on
-.Dv hook
-are transmitted out on the tty device.
-No modification to the data is performed in either direction.
-While the line discipline is installed on a tty, the normal
-read and write operations are unavailable, returning
-.Er EIO .
-.Pp
-The node supports an optional
-.Dq hot character .
-If set to non-zero, incoming
-data from the tty device is queued until this character is seen.
-This avoids sending lots of mbufs containing a small number of bytes,
-but introduces potentially infinite latency.
-The default hot character is 0x7e, consistent with
-.Dv hook
-being connected to a
-.Xr ng_async 4
-type node. The hot character has no effect on the transmission of data.
-.Pp
-The node will attempt to give itself the same netgraph name as the name
-of the tty device.
-In any case, information about the node is available via the netgraph
-.Xr ioctl 2
-command
-.Dv NGIOCGINFO .
-This command returns a
-.Dv "struct nodeinfo"
-similar to the
-.Dv NGM_NODEINFO
-netgraph control message.
-.Sh HOOKS
-This node type supports the following hooks:
-.Pp
-.Bl -tag -width foobar
-.It Dv hook
-.Xr tty 4
-serial data contained in
-.Dv mbuf
-structures, with arbitrary inter-frame boundaries.
-.El
-.Sh CONTROL MESSAGES
-This node type supports the generic control messages, plus the following:
-.Bl -tag -width foo
-.It Dv NGM_TTY_SET_HOTCHAR
-This command takes an integer argument and sets the hot character
-from the lower 8 bits. A hot character of zero disables queueing,
-so that all received data is forwarded immediately.
-.It Dv NGM_TTY_GET_HOTCHAR
-Returns an integer containing the current hot character in the lower
-eight bits.
-.Sh SHUTDOWN
-This node shuts down when the corresponding device is closed
-(or the line discipline is uninstalled on the device).
-The
-.Dv NGM_SHUTDOWN
-control message is not valid, and always returns the error
-.Er EOPNOTSUPP .
-.Sh BUGS
-The serial driver code also has a notion of a
-.Dq hot character .
-Unfortunately, this value is statically defined in terms of the
-line discipline and cannot be changed.
-Therefore, if a hot character other than 0x7e (the default) is set for the
-.Nm
-node, the node has no way to convey this information to the
-serial driver, and sub-optimal performance may result.

-.Sh HISTORY
-The
-.Nm
-node type was implemented in
-.Fx 4.0 .
