With the help of a few on this list and Ten Tec's customer support I can now control frequency changes on the Paragon II with Ham Radio Deluxe and Commander from DXLabs. I used an off-the-self NULL modem cable and configured the rig as an Icom 765 with a CVI address of 2C. 1200 baud, 8, 1, no parity. Thanks to all. 73 Paul
