I need to touch external hardware through the parallel port and so far, doing that hasn't been a problem. Now, I need to control the timing of signals sent to the external hardware. I can sucessfully create a 50 millisecond pulse using the 8259 clock stuff, but I have no clue how to generate a shorter than 1 millisecond signal. I now need a 10, and a 50 MICROSECOND signal and I'm not sure if I can.... IS it possible? For the curious... I need to toggle a single data bit on the parralel port with an on time of 50milliseconds.
