It's time to update a ten year old shack, and the new computer has one real serial port and the rest are USB (serial bus) ports. So, I want to connect my TenTec Orion II to this. Are there any tricks to doing CAT Radio Control, CW keying or the TenTec USB-sound-card interface through USB? How do I map the COM ports listed in DX4WIN to USB? Thanks! 73, Byron
