I have 4 USB ports on this computer and one external 4-USB hub. I have rearranged the connectors so that the external hub only connects to the printer and leaves 3 open USB's. I connect the USB serial adaptor to one of the connectors on the computer. Hope this makes sense. Thanks again for you help in this matter. Here is the output:
