NAME

       sttydefs - maintain line settings and hunt sequences for TTY ports

SYNOPSIS

       /usr/sbin/sttydefs -a ttylabel [-b] [-f final-flags] [-i initial-flags] [-n nextlabel]

       /usr/sbin/sttydefs -l [ttylabel]

       /usr/sbin/sttydefs -r ttylabel

DESCRIPTION

       sttydefs  is an administrative command that maintains the line settings and hunt sequences for the system's TTY ports by making entries in,
       and deleting entries from the /etc/ttydefs file.

       sttydefs with a -a or -r option may be invoked only by the super-user. sttydefs with -l may be invoked by any user on the  system.

OPTIONS

       The following options are supported:

       -a ttylabel	       Add a record to the ttydefs file, using ttylabel as its label. The following describes the effect of  the  -b,  -n,
			       -i, or -f options when used in conjunction with the -a option:

       -b		       Enable  autobaud.  Autobaud  allows  the  system to set the line speed of a given TTY port to the line speed of the
			       device connected to the port without
				the user's intervention.

       -f final-flags	       Specify the value to be used in the final-flags field in  /etc/ttydefs. final-flags must be in a format	recognized
			       by the stty command. final-flags are the termio(7I) settings used by ttymon after receiving a successful connection
			       request and immediately before invoking the service on the port. If this option is not specified, sttydefs will set
			       final-flags equal to the termio(7I) flags 9600 and sane.

       -i initial-flags        Specify	the value to be used in the initial-flags field in  /etc/ttydefs. initial-flags must be in a format recog-
			       nized by the stty command. These flags are used by ttymon when searching for the  correct baud rate. They  are  set
			       prior  to  writing  the	prompt.  If  this  option  is  not specified, sttydefs will set initial-flags equal to the
			       termio(7I) flag 9600.

       -n nextlabel	       Specify the value to be used in the nextlabel field in /etc/ttydefs. If this option is not specified, sttydefs will
			       set nextlabel equal to ttylabel.

       -l[ttylabel]	       If  a  ttylabel	is specified, sttydefs displays the record from /etc/ttydefs whose TTY label matches the specified
			       ttylabel. If no ttylabel is specified, sttydefs displays the entire contents  of  /etc/ttydefs.	sttydefs  verifies
			       that each entry it displays is correct and that the entry's nextlabel field references an existing

       -r ttylabel	       Remove any record in the ttydefs file  that has ttylabel as its label.

OUTPUT

       If successful, sttydefs will exit with a status of 0. sttydefs -l will generate the requested information and send it to standard output.

EXAMPLES

       Example 1: A sample of sttydefs command.

       The following command lists all the entries in the ttydefs file and prints an error message for each invalid entry that is detected.

       example# sttydefs -l

       The following shows a command that requests information for a single label and its output:

       example# sttydefs -l 9600
       ------------------------------------------------------------------
       9600:9600 hupcl erase ^h:9600 sane ixany tab3 hupcl erase ^h::4800
       ------------------------------------------------------------------
       ttylabel: 9600
       initial flags: 9600 hupcl erase ^h
       final flags:   9600 sane ixany tab3 hupcl erase ^h
       autobaud: no
       nextlabel:      4800
       The following sequence of commands will add the labels 1200, 2400, 4800, and 9600 and put them in a circular list:

       sttydefs -a 1200 -n 2400 -i 1200 -f "1200 sane"
       sttydefs -a 2400 -n 4800 -i 2400 -f "2400 sane"
       sttydefs -a 4800 -n 9600 -i 4800 -f "4800 sane"
       sttydefs -a 9600 -n 1200 -i 9600 -f "9600 sane"
