Hi,

I have created a software that controls a door access system through my parallel port. I have managed that writing to the parallel port using a IO.DLL file. The software works fine in Windows 98 however when I tried to use it in Windows 2000 it crashes. The parallel port doesn't work in Windows 2000. Any ideas why is that? Any possible solutions that I can overcome this problem?

Please advice!
Thanks,
H.
