You'd need to hack together some other kind of interface. There is a parallel port <-> Commslink adapter designed by FreeWing, and I think their Saturn comms program (SSLINK? Not sure that's the name but it's something like that) supports it. It needs several logic circuits - two 8-bit latches, a 7474, and an 8-to-4 multiplexer if I'm not mistaken, as well as several diodes (this supports a standard parallel port; the design could probably be simplified for a PS2/ECC/EPP mode port). My connection is acting up a bit at the moment, but a google search for "PAR_HARD" should turn up several sites with the schematic package.
