The following request is nothing to do with me. I'm posting it for my
boss 'cos he doesn't understand how to use Pnews :-) 
Please reply to - pat@castle.ed.ac.uk 

We have PC AT running OS/2 (currently version 1.1), and a PC card 
for X.25 which we have modified.  Our card is memory mapped at
C8000 Hex onwards for 32K, and uses no I/O ports.
We have an MS_DOS program to download and use the card, written in
C.  Since the card sits in REAL address space, we don't know
the easiest way of accessing it from within the a program ---
is there an OS/2 operating system call or technique which we
could use to get access to this window of real memory?
