Why do you want a kernel module? Can't I just use the 'outb' command in c (#include "asm/io.h" or so)? of course this requires root priviliges, but that's probably not a problem when you're even allowed to stick your own hardware in the parallel port :) > The parallel port pinout is in the pc-hardware faq on usenet. I found an easier way: just putting a led and a 470 ohm resistor (serially) between the data connector and one of the 'ground' ('earth'?) connector of the parallel port. > > I don't want to kill my serial ports :) > > They're the robust ones. Take good care of your parallel port. Arnout
