That is not an application software matter - it is something the radio manufacturers will need to fix in their CAT implementations. There is not a single radio that is capable- in either hardware or software - of reliably servicing two different radio control applications. To do so, several changes are needed in the current radio firmware and interface: 1) commands/responses must be unambiguous - each response must identify not only the nature of the response but what command from which application the data is responding to. 2) the radio must become the "master" of all communications on the control bus. The radio must contain a system under which (a) each controlling device is assigned a "time slot," (b) the radio polls each controlling device, or (c) control is implemented on a shared BIDIRECTIONAL bus WITH COLLISION CONTROL. 3) each controlling program must be able to hear commands from very other controlling program and must respond to the data from the radio (update the program's internal status) as if it had issued the commands. I suspect you will find most application software authors happy to support a properly designed interface protocol. I would not expect any software writer (or group of writers) to create full full function "virtual radio servers" for every new (and old) radio to come along. 73, ...
