Parallel port in windows xp

[Guest]

I have a problem with dos application running under windows xp.
Application uses parallel port hardlock. While running “start
optimalization†option, program checks hardlock present and makes
optimalization. In theory everything is ok, but
application sends thousand’s 1 bit information’s on parallel port. This
causes that application works 70% slower. Can you help me ?

have you contacted the vendor of the "hardlock" yet. I would believe
they have seen this behavior before.

You need to contact the manufacturer of the hardlock application.

I suspect that the application is trying to access the parallel port
device directly without using operating system function calls. Windows
XP prohibits applications from directly accessing the hardware,
although the 9x versions of Windows (95/98/Me) did allow it.

Good luck
