NAME
sttydefs - maintain line settings and hunt sequences for TTY ports
SYNOPSIS
/usr/sbin/sttydefs -a ttylabel [-b] [-n nextlabel] [-i initial-flags]
[-f final-flags]
/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 a privileged
user. sttydefs with -l may be invoked by any user on the system.
The options have the following meanings:
-l If a ttylabel is specified, sttydefs will display the record
from /etc/ttydefs whose TTY label matches the specified
ttylabel. If no ttylabel is specified, sttydefs will display
the entire contents of /etc/ttydefs. sttydefs will verify
that each entry it displays is correct and that the entry's
nextlabel field references an existing ttylabel.
-a ttylabel
Adds 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 Specifies that autobaud should be enabled. 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.
-n nextlabel
Specifies 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.
-i initial-flags
Specifies the value to be used in the initial-flags field in
/etc/ttydefs. initial-flags must be in a format recognized
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(7) flag 9600.

-f final-flags
Specifies 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(7) 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(7) flags 9600 and sane.
-r ttylabel
Removes 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 the standard
output.
EXAMPLES
The following command will list all the entries in the ttydefs file
and print an error message for each invalid entry that is detected.
sttydefs -l
The following shows a command that requests information for a single
label and its output:
# 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"
