I'd appreciate similar information about both parallel and serial
ports.

To be more specific, I'd like to be able to use the ports from C
programs (microSoft C 5.1 at the moment) but I'm not super-familiar
with PC's and where to find the information that I need.

Any help will be sincerely appreciated.  E-mail is prefered for I
can't seem to keep up with news.  Sigh...

If I receive useful information, I'll happily summarize for the
net.

Thanks.

Best,
