I cobbled together a kernel module to do this on the parallel port,
and a python module to drive the driver, plus a python program to
test it.
A kid next door used it with a Tk gui that he wrote to drive model
trains at a church fete. You've reminded me that I'll have to revise
it for the 2.2 kernel by next summer unless he learns quickly.
The parallel port pinout is in the pc-hardware faq on usenet.

They're the robust ones. Take good care of your parallel port.
