Now in order to get the 5v level, I set the parallel port to EPP in the BIOS. That does seem to make the hi level 5v, but Mach3 no longer commands the hi-low switch on any of the pins.

Would I need to reinstall Mach 3 and the driver after switching the EPP setting?
I tried reinstalling Mach 3, it didn't seem to help..
