[comp.sys.ibm.pc] Documentation Needed HELP!!

rgcote@mit-vax.LCS.MIT.EDU (Rob Cote) (03/17/88)

I am in dire need for some documentation for the IBM PC Bisynchronous
card (the synchronous serial communications board). Now before you hit
the 'n' key because you've never heard of it, I am looking for any
books, articles, technical references, example program sources or
other documents relevant to programming IBM PC communications, since
any of it could potentially lead me to what I am looking for.

What am I trying to do is write a simple program that will read
characters from the synchronous port of a PC (connected to a 4.8Kbit
synchronous modem) and write the characters out to the asynch port. I
have the 3 volume IBM PC Technical reference which actually does talk
about programming the BSC card, but it is missing some key
information. It doesn't tell enough about the interrupts for me
to change the vector or what I should set the timers to. Since my
experience with PC programming approaches nil, I am not able to write
the required software from the information given.

Any help would be *greatly* appreciated. I am really getting desperate
for this information (and my boss would very much appreciate this 
program being completed :-)). 

Please send email, even though I will try to scan this news group for 
the next few days.
