Well, in defense, I inherited this code which was written around
1998-2000 (the Windows version, anyway; DOS version has been around
since about 1985).
I poked around a bit looking for the DevCon samples. Nno joy; the CDs
apparently are long gone and my quick Google came up with very little.
So the questions now are:
1. Will the DevCon routines support Win98 SE, Win2K, and WinME? (all
of which our software currently does support)
Win2K for sure, I'm not sure about Win9x/ME. You can try it and see.
2. Are the queries as simple as the 'CreateFile' (the 'naive' way to
do poll the ports)?
No, it's actually quite involved, unfortunately.
3. Is there a resource on the web I can use to get good examples of
these DevCon queries?
You can download the .exe from http://support.microsoft.com/kb/311272, which
tells you where to get the source code in the DDK.
