USB to Serial Adapters

Not all USB to Serial Adapters are created equal. When I upgraded my computer several years ago, I purchased an IOGear GUC232A. It worked with my Zephyrus receiver, however, every once in a while, the serial port would simply lock up. When this occurred, I had to reboot my computer to get the serial port back working. If I stopped and stop the serial ingest program rapidly, the port would lock up.

I picked up a new MFJ USB to Serial Adapter recently and installed it over the weekend. I have not had a lock up with it yet. The MFJ unit is based on the FTDI chip set.
