Parallel Port on XP



Hi All,

I have a simple Stepper Motor Controler that uses Parallel port for
connection. I had no problem using it with Win98 but now with WinXP
story is different.

The problem I have is not protection issue in NT/XP OSes. The problem
is as soon as I connect my cable to parallel port, my steppers motors
lock down. It seem parallel port is sending some signal regardless of
having any program running or not.
If I boot from Win98, everything is good.

Something is setting my parrallel pins to Hi and Low without having any
program running (and no prointer is defined). Any idea?

P.S. I have already ran UserPort.exe hack to release the protection.

.
