I'm wondering if this is possible or not.

    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.
