Hello!
I have little knowledge about parallel port programming on Linux. I wan't to know if its possible to like 'listen' if the current is incoming into data pin? What I need is forexample I have two wires, one from Data pin 1 and other from ground, if I put them together some function will return for example 1 else 0! Does anybody know something about this function!? I think its called inb(); Thanx!
