    Sorry if I didn't explain the problem clearly. The card I'm trying to
    use is an Add-On PCI card, not the one built onto the motherboard.
    Since it's an add-on, the motherboard's BIOS doesn't know it exists.

    Windows sees it and can use it just fine once it loads the driver for
    it. When I try to use the port while running Java, Java it doesn't see
    it.

    I have tried to use the standard COMM and rxtx-2.0.5-win32, but I
    still cannot see the port.

    Thanks,

    Mike C.
