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