Compatibilty Mode

[David Buckner]

I have an old 16 bit application that will not run on XP
or 2000. It runs fine under 98 and 95. I have tried
using the compatibilty mode feature with no luck. The
app starts but then when it tries to access the com port
I receive a General Protection fault. I am a domain
admin on the machine so there should not be any rights
issues. I am no programmer so if one of you programming
wizards has any insight it would be greatly appreciated.

TIA,
David

I work with a similiar type of situation. Setting to follow
other versions of windows was no joy. Ended up working by
just checking the 256 colors box

Thank you. Is there a way to allow the program to access
the port directly instead of using virtual ports?

I did try that but it still gives me the GP when I try
and connect to the com port. The app runs fine excpet
for comm port communications.

If, as it appears, the program is trying to handle hardware ports
directly, then it absolutely will *not* be allowed to run under XP.
Those 'behind the system's back' accesses were one of the principal
causes of instability in 9x, and are not allowed.
