System Administration Commands sttydefs(1M)
NAME
sttydefs - maintain line settings and hunt sequences for TY
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 TY 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
TY 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 recog-
nized by the stty command. final-flags
are the termio(7I) settings used by
ttymon after receiving a successful con-
nection 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 TY 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 refer-
ences 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

System Administration Commands sttydefs(1M)
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"
