I have a dell Latitude D600 laptop that will only transmit data to connected device through the serial port when a port replicator is attached. When port replicator is removed, the laptops serial port will not send any data to attached device. Anything I can do to get the serial port to operate correctly?
Check your BIOS settings to make sure the serial port is recognized. It will be under the same title as the other ports. Sometimes they ship disabled because most people do not use them...they use the USB ports..hope this helps.
Please rate this solution.
Boot to the bios (system setup).. locate serial port there and make sure it is turned on
