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.
OPTIONS
-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 for-
mat 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 recog-
nized by the stty command. final-flags are the ter-
mio(7) settings used by ttymon after receiving a suc-
cessful 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 ttyla-
bel as its label.
DIAGNOSTICS
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"
