getty(1M) System Administration Commands getty(1M)NAMEgetty - 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
DESCRIPTIONgetty 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 expan‐
sion 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 charac‐
ter (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.
