SSTTY(8) BSD System Manager's Manual SSTTY(8)NAMEsstty - Equinox SuperSerial Technology sstty utility
SYNOPSIS
/usr/sbin/sstty
DESCRIPTION
Sstty gets Equinox specific information about a device or set flags that
can be selectively turned on or off, in a manner similar to the standard
UNIX stty command.
To see a complete list of options available with the command, enter sstty
without options. This entry lists the correct usage and options avail-
able for the sstty command. The commands are: sstty-a reports current
settings of sstty options
sstty-c display Equinox SST configuration
sstty dtr [0,1] force DTR (1 = on, 0 = off)
sstty [+ - ] fb permit FoxBase+ to operate without requiring hardware
flow control
sstty-i display ISA memory hole status table
sstty [+ - ] lb initiates a hardware (physical) port loopback
sstty [+ - ] lck lock/unlock port stty settings
sstty [+ - ]li, lo force/prevent use of line discipline processing
sstty[+ - ] lp printer port, force open, do not close
sstty-m display port modem signals
sstty [+ - ] pc permits WordPerfect 5.0 to operate without requiring
hardware flow control
sstty +rs resume output on a flow-controlled port
sstty-s display status of port tty [1a0- 8hf]
The sstty-a command, similar to the stty -a command, reports the set-
tings of the sstty options. The output is similar to the following, de-
pending on how a particular system is set up: -ixon -ixany -fb -lp -li
-lo -cts -rts -pc -xprn -lb -xon -sscrn -lck -hs
The sstty-c command displays the Equinox SST hardware configuration. It
identifies the logical adapter card number(s), the slot(s) or I/O ad-
dress(es), and the adapter card type(s) for all adapter cards that are
installed and configured.
The sstty +li command turns on standard line discipline processing on in-
put.
The user can force the DTR control signal high using this sstty flag.
Setting this parameter (sstty dtr 1) forces DTR to be true regardless of
the application. Use sstty dtr 0 to return normal operation of the DTR
control signal.
The sstty +lb flag is a diagnostic tool used to initiate physical hard-
wire loopback designed for testing wiring. Redirecting the sstty +lb
command to a terminal, places the SST port in loopback mode. This is a
good test for the wiring and hardware because characters typed at the
terminal are echoed back to the terminal. If no characters are displayed
at the terminal, this may indicate a wiring problem. To return the termi-
nal to normal mode, enter sstty-lb. Do not enter the sstty +lb command
from a terminal. The terminal is placed in loopback mode and no more
commands can be entered! Powering the terminal off and on does not help.
Always redirect the sstty +lb command from the console to the port to be
tested.
Entering sstty +lck locks a port's parameters (speed, character size,
etc.). After this command is entered any stty changes to the port will
be ignored. To return a port to normal operation enter sstty +lck. The
device driver bypasses standard line discipline processing wherever pos-
sible for enhanced performance.
