NAME
getty - set terminal type, modes, speed, and line discipline
SYNOPSIS
/usr/lib/saf/ttymon [
-h] [
-t timeout]
line [
speed [
type [
linedisc]]]
/usr/lib/saf/ttymon -c fileDESCRIPTION
getty sets terminal type, modes, speed, and line discipline.
getty is a
symbolic link to
/usr/lib/saf/ttymon. It is included for compatibility
with previous releases for the few applications that still call
getty directly.
getty can only be executed by the super-user, (a process with the user
ID root). Initially
getty prints the login prompt, waits for the user's
login name, and then invokes the
login command.
getty attempts to adapt
the system to the terminal speed by using the options and arguments
specified on the command line.
Without optional arguments,
getty specifies the following: The
speed of
the interface is set to 300 baud, either parity is allowed,
NEWLINE characters are converted to carriage return-line feed, and tab expansion
is performed on the standard output.
getty types the login prompt before
reading the user's name a character at a time. If a null character (or
framing error) is received, it is assumed to be the result of the user
pressing the
BREAK key. This will cause
getty to attempt the next
speed in the series. The series that
getty tries is determined by what it finds
in
/etc/ttydefs .
OPTIONS
The following options are supported:
-h If the
-h flag is not set, a hangup will be forced by
setting the speed to zero before setting the speed to the
default or a specified speed.
-t timeout Specifies that
getty should exit if the open on the line
succeeds and no one types anything in
timeout seconds.
-c file The
-c option is no longer supported. Instead use
/usr/sbin/sttydefs -l to list the contents of the
/etc/ttydefs file and perform a validity check on the file.
OPERANDS
The following operands are supported:
line The name of a
TTY line in
/dev to which
getty is
to attach itself.
getty uses this string as the name
of a file in the
/dev directory to open for reading
and writing.
speed The
speed argument is a label to a speed and
TTY definition in the file
/etc/ttydefs. This definition
tells
getty at what speed to run initially, what
the initial
TTY settings are, and what speed to try
next, (should the user press the
BREAK key to
indicate that the speed is inappropriate). The
default
speed is 300 baud.
type and
linedisc These options are obsolete and will be ignored.
