I build the pc2jamma power relay circuit and everything works great in ArcadeOS and with Montest, but arcmon does not seem to trigger the parallel port hardware. Is there a program out there like Montest, but one that turns the circuit on or off from the command line. I have tried sending 00 or ff to the port, but it sending data in this manner doesn't seem to duplicate what montest and arcadeos are doing.
I have also tried switching port types (ECP.EPP,both) with no success.
