    Hi all,

    I've got some problems with my parallel port... I use it to control relays
    but when I write "0" (Labview application) it doesn't stay and change to
    "1" in less than 1s !!!! (Win98 SE)

    When I do the same thing in dos mode it works normaly

    Thanks for your help

    Check that the port settings in your bios are set for standard
    parallel port and not enhanced etc, I have seen various dongles get
    tripped up with the same trouble and have had various issues with this
    on several motherboard/windows combinations in the past myself.
