The source to the tty driver for the mv162 seems to only cover the
baud rate in its hardware-specific portion.  If you are REALLY stuck, you
can cheat by accessing the 8530 serial controller directly or adding the
proper IOCTL code to z8530Serial.c in you vxWorks distribution and
recompiling it.  Either way, you will want to use the 8530 driver as
an example of how to use the chip.

FYI -- I have a note here about a patch from wind rivers about the serial
controller.  I don't recall the details, you might want to contact them
about it.  I seem to recall something about the LX board being different
and/or broken.  I don't want to start any panics here, contact WRS first...
I don't recall the details.
