Re: Parallel Port Wigglers PCI Cards and XP
You didn't mention your intended application, but assuming it is a
piece of equipement it is possible that you are running into a timing
issue. My company purchased an emulator / compiler system back in
2002, which uses a parallel port dongle (gag - ack) for the compiler.
In order to get it to work, it was necessary to run a utility that
slowed the timing of the parallel port down and the faster the
processor in the computer the larger the scaling factor had to be.
