The 7300 and the 7200 are connected by USB (Silicon Labs CP210x USB to URART bridge- Icom ver 1.30 USB driver) cable.
Both the 7200 and the 7300 have both the "CI-V Transceive" disabled.
The Flex 5000A connects to the computer thru a firewire cable.
The Flex, and the IC-7300 work just great with Commander , I just having issues with the IC-7200.
The main issue I have with the IC-7200 is being able to transmit both voice and data. it seems to be an either or situation
