Serial Ports, Com Ports and USB

    I am trying to connect a device that has a serial port connector to a Vista
    computer. I got a converter to plug it into a USB port. When I plug it in I
    get a message that it recognizes the device(converter) and has installed the
    drivers. When I try to use the hardware that uses the serial port I get a
    message that it cannot find a com port. I have tried to manually connect it
    to every com port the hardware's software offers, but no luck. How can I
    make this thing find a com port?

    Thanks for your help.

  2. You may need to enable something in the BIOS since no serial port was
    provided on the mobo.

    What do I enable in the BIOS?

  4. Find out what COM port number the device has assigned to its virtual COM
    port - it may be a higher port number than the device or its software will
    support. I have seen these things take up COM ports as high as 11 or 12.

    Read the manual that came with the COM to USB port adapter to see how to get
    and change the port number it's using. You may also be able to change it by
    going to Device Manager, expanding the Ports section, finding your device,
    right-click it and select Properties, then look at the Details tab and maybe
    an Advanced button if one is located there.

  5. Since you gave no details about your computer at all I doubt anyone really
    knows. But hopefully you can look at the manual for the mobo or download it
    from the mfg's website and look through it for items relating to serial

    Don't you see the COM port number in the device manager?
    Open up the dev. manager, expand the Ports category. It should be there.
