Jerry,
You didn't specify what version of UNIX (or even Xenix) that you
were using.  If you were using Xenix 3.X, for example, there is
a rdchk() function that allows you to see if any characters are
available on the input queue.  Respond and you can get a little more
detail.  By the way, take a more detailed look at the tty section
of devices and the ioctl() call in the ref. manual.  These will help
you.

ps - Do you know a person by the name of Adolph Fejfar or Mike Corin
who work for MITRE-Bedford, but at the Ft. Huachuca, AZ. site?  Just
curious to see how small a world it *actually* is...
