Proposal: CAT serial/USB interface

[gpanico]

Hi guys,

I was wondering if it would be possible to implement a CAT interface via USB or UART (in such case via a MAX232 adapter) to pilot the radio from a PC.

I don't know if the Arduino while running the radio-code can also "listen" to the USB or to the UART and run some function, like on old microcomputers the UART I/O was triggering an interrupt that could be trapped. Or maybe in the main loop we still have some milliseconds to spare?

Would that be technically feasible?
