You could also use the PortIO library from the OpenG project
http://www.openg.org.
It is currently only in the CVS source code
repository on that site and not yet part of the OpenG Toolkit. Because
it is not everybodys thing to use CVS I include that library as
attachement here.
I tested it myself on Win95, NT4, 2000 and XP and had no problems at all
with it. But please consider it beta software and if you have problems
let me know with as much details as possible.
