Hi,

  I have a pic sending data to the lpt port on a pc. Does any one know of
any info on lpt pass through. Like copy protect dongles plug in the lpt and
the printer plugs in the back of the dongle, and they work together (most
of the time). I am useing pin 10 (ack on lpt port) to send data from the
pic to the pc.

Thanks

Glen Benson
