Several weeks ago, there was posted a code fragment demonstrating a
(fairly) SYSV portable way of testing for pending (unread) characters on
stdin (from the terminal).  My vague recollection is that the code
invoked a couple of innocuous UNIX system calls with obscure arguments
designed to Raise The Beast (just kidding...}:-> )

We have similar code in place for the BSD and MS-DOS version of our
application software, but now we need it for a SYSV port (to the 3B
series, no less).  Of course, I lost the original posting, and my
previous request for this fragment elicited no responses (I suspect the
request met with the Great West Cost News-Quake). 

Would some please, no,, PLEASE mail me the that code fragment?  Or at
least a hint at the solution?  As before, I'll forward responses to
those who mail me requests (I have 3 or 4 request so far- I haven't
forgotten you).

Thanks for the help!
