Other Devices Setup
-h
Hangs up the pseudo-tty if the TCP connection is lost. This
mimics the situation in which a real serial port loses a
signal such as DCD. In the same manner as the serial port,
a SIGHUP signal will be sent to all processes that have the
slave pseudo-tty as their controlling tty. See the
-w option.
-n
Converts all carriage-returns read from the client process
to carriage-return and line-feed. This is useful if using
ioland for printing and the print job is off the right
margin (i.e. ‘stair stepping’).
-m
Push the STREAMS tty modules onto the slave pseudo-
tty. This is useful for applications that expect to modify
tty parameters as if a hardware device was attached.
The modules pushed are the line discipline (normally
called
ldterm) and the hardware emulation (if
supported). This option requires that the pseudo-tty
architecture is based on the STREAMS I/O mechanism.
The recommended Unix variants for using this option
are those based on System V Release 3. Variants based
on System V Release 4 should first try the
-a option.
Variants such as HP-UX, AIX, XENIX and SunOS do not
require either option.
-a
Use the autopush facility to push STREAMS modules
onto the slave pseudo-tty. This facility is supported on
Unix System V Release 4 variants.
-u
Discard all data received from the peripheral. This is
useful in cases where the peripheral is sending
unwanted data to the host, which is not being read by
the client and therefore may cause blockage problems
on the pseudo-tty.
-w
Used with the
-h and -p options. By default, on a hang-
up, the daemon will open a new pseudo-tty before it has
reconnected to the IOLAN+ port. This option does the
opposite and tries to re-establish the TCP connection first.
