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 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.
