And... drvSerial assumes that you have a standard vxWorks ty driver for
your serial I/O hardware - and that you create named devices within VxWorks
(for example: /dev/co, /dev/fs2, etc).

To the best of my knowledge, Keck has a driver for the Force SIO-2 VME
board. I created a driver also meant to be called from drvSerial (based on
what was in HiDEOS) for the GreenSprings Octal-232,422, and 485 IP modules.
See:
http://www.cfht.hawaii.edu/~tcs/tcsiv/tygsoctal.html for details and links
to FTP sites. 

Also included is a simple device support layer (devNode/drvNode) that
doesn't  support prompts as drvAscii does but understands the concept of
multiple string ers (as did HiDEOS).
