Is this a USB to RS232 adapter ? Do you have any entries in Device Manager at all ? There is no point in doing any further testing, unless the hardware shows up in Device Manager. If it does, then at least the USB interface on it is working. http://i137.photobucket.com/albums/q207/smrman/devicemanprolific.jpg ******* Have you tested it using Hypertrm in Windows ? (Note - there is no point trying this, unless you can see a new COM port for your adapter, in Device Manager.) There is some information on RS232 here. http://www.wiehes.com/techinfo/RS232.html You would take a wire and connect RD to TD (receive data to transmit data). That is a "loopback" connection. Since the test is being done in Hyperterminal, there is no need to connect up the flow control signals. You may be able to get some results with a single wire. In Windows, using something like Start : Programs : Accessories : Communications : Hyperterminal then set it up to communicate to the new adapter, while a wire is connected from pin 2 to pin 3. If you do that correctly, then when you type in Hyperterminal, you should see letters appear in the Hyperterminal window. For default settings, you can use 9600 baud, 8-N-1. Hyperterminal may not be available in all versions of Windows. I think my copies of WinXP and Win2K have it, but I don't know if Vista or Windows 7 include it or not. It is convenient for tests of this nature. Paul

That loops back what you type, to the same adapter. As long as you get the correct two pins (Transmit Data and Receive Data), you can test that a typed character, is returned back to the adapter.
