System Administration Commands getty(1M)
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 file
DESCRIPTION
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 par-
ity 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 speci-
fied 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 con-
tents of the /etc/ttydefs file and perform a
validity check on the file.
OPERANDS
The following operands are supported:
line The name of a TY 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 read-
ing and writing.
speed The speed argument is a label to a
speed and TY definition in the file
/etc/ttydefs. This definition tells
getty at what speed to run initially,
what the initial TY 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.
