Disconnect the serial connections and loop the RPi's Tx and Rx pins. Test that what you type is echoed back on the screen. If/when that is working reconnect RPi Tx to fona Rx and RPi Rx to fona Tx.

Is there a test it could perform and then branch to native vs. emulation? And wouldn’t compilers need to support that? I’m guessing it must be similar to code ...

I recently installed RPiOS (64 bit) on an RPi 4 with 4 Gb. The system was upgraded via apt on July 31, 2020.
