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 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 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 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 indi‐
cate that the speed is inappropriate). The default speed is 300
baud.

type and linedisc
These options are obsolete and will be ignored.
