For example, the above code sends "PROGRAM" to the radio to initiate cloning, but then aborts with an "Unsupported model" error. The printing of "response" show that it is "nul", but my port monitor clearly show that "QX\x06" was returned.

Without looking, I think _echo_write() writes something to the device, and then, expecting a complete echo, reads and discards the same number of characters so that the caller doesn't see the echo. Maybe this new radio/cable doesn't echo and your response is getting eaten and discarded?

Thanks. I think I follow what you are saying. That makes sense because when it gets to downloading the "chunks" it CHIRP there are fewer characters than expected (they to got eaten and discarded.
