I've been making an electronic device (in a protoboard -to test it-) to simulate a remote Control for the DVD.
I input the codification of the keys through the parallel port. So, my "driver", checks periodically the port to see
if any key was pressed. Everything works great, but I just want whether anybody knows how to make a
HARDWARE INTERRUPT so that I don't have to check the port continuosly. I could use the IRQ 7 (the one
that uses the parallel port), but I have no clue how to detect the INTERRUPTION and proceed with the
decodification of the key that was pressed. Any idea would be welcome.
