> Use two serial ports on the Pi. One talks to the radio, one talks to the
PC.
That's exactly what I do with my Arduino,

Here's the actual firmware,
#define PX3_RX_PIN 7
#define PX3_TX_PIN 5
#define PC Serial
SoftwareSerial PX3(PX3_RX_PIN, PX3_TX_PIN);
void loop() {
while (PC.available())
PX3.write(PC.read());
Usb.Task(); // process keyboard, mouse, thumb drive and knob
while (PX3.available())
PC.write(PX3.read());
}
I remove my microcontroller from the PC - PX3 path in downloading new
firmware to the PX3 and/or KX3 in order to ensure the most reliable
connection.
