Hallo Bogax,

The solution is quite simple: Use all lines (except GND of course). 
Connect all lines thru a diode with eachother. The moment RESET is (L), 
the others become (H) just because of the RESET. 
I use the same trick to draw power from the COM-port(s) for small device 
to be attached to the COM- or LPT-port.
