(Is this the source of the "W (541151) cellular: UART hw fifo overflow" I see periodically?)

Yes, and you'll often see "gsm-mux: Frame error: EOF mismatch" log lines in combination with these.

I also added counters for these, you can query them with the "simcom status debug" command:

OVMS# sim stat deb
