NAME
getty - set terminal type, modes, speed, and line discipline
SYNOPSIS
getty [-h] [-t timeout] line [speed [terminal [linedisc]]]
getty -c file
DESCRIPTION
getty is included for compatibility with previous releases for
the few applications that still call getty directly. getty
can only be executed by a process with the appropriate
privileges. 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.
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.
-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 specified speed.
-t timeout
specifies that getty should exit if the open on the line
succeeds and no one types anything in timeout seconds.
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 indicate, by pressing the BREAK key,
that the speed is inappropriate. If not specified on
the command line, speed defaults to the first entry in
/etc/ttydefs.
terminal
The terminal option is the name of the terminal type.
linedisc
The linedisc option is the name of the line discipline.

-c file
The -c option performs a check on the gettydefs file.
When given no optional arguments, getty specifies the
following: The speed of the interface is set to the speed
defined in the first entry in /etc/gettydefs, either parity is
allowed, new-line 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.
NOTICES
Administrators and developers are encouraged to use ttymon(1M)
as support for getty may be dropped in the future.
