    Yes Microsoft Windows calls it a DCC connection with a DCC cable. This is
    the same as the LapLink cable as I understand it. There is a company that
    has a product called a "DirectParallelŽ Universal FAST Connection Cable" @ ... This cable is supposed to go pretty fast. IIRC,
    there is some extra circuitry in the cable that got it up to fast speeds.
    However, they will not acknowledge that Linux exists in the computing world.
    No support whatsoever for Linux. I think they are forbidden from doing so
    another company that provides them with enough incentive to stay thinking
    that way. ;-) Therefore, those are two Microsoft Windows ONLY ways.

    You could look into running PLIP between Linux and Windows. I have seen
    some folks say it could be done. For me it was easier to implement my own
    simple way of sending a nibble at a time on the LapLink / DCC cable.
