sttydefs
sttydefs(1M) System Administration Commands sttydefs(1M)
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"
