 I was able to compile PDTerm without any difficulty.  I don't recall having
to add the EXTio routines either.  One thing that might be of interest to
those using the PD terminal programs (and MaxiComm): I was able to modify
PDTerm in under an hour (it is well written, if undocumented) so that it 
runs at 1200 baud easily and very likely many times faster.  The key to the
speed of these programs is the overhead in message handling.  PDTerm requires
two messages to be sent for a single character to be sent from the serial
port to the screen.  The same is true going the other way.  At 1200 baud that
is over 400 messages per second.  That would require lots of task switching
and the overhead involved.  I modified PDTerm so that it will try to send
characters in chunks of up to 10.  This can greatly reduce the overhead, and
increase the speed.
 At the moment I am attempting to add a sophisticated file capture routine to
PDTerm and when I am done I will send it to the net.
