The parallel port can be used by interruptions, i.e. like the serial port?
I need to take time measurements of an even that occurs outside the PC, and it makes its input via the parallel port. I made a do ... loop and check the port in every instance, but the time measurement comes out not accurately enough, so I thought I could work by interruptions. I heard some time ago that i could be done.
Any help would be greatly appretiated.
