I will try; but as you recall, I've had problems with MM under GDB on this
platform since it greatly impacts the performance and affects timeouts, etc.

I'll get you a full log in any case; might be a day or two.

Quectel EM12-AW; it is pretty similar to other Quectel modems.

Obviously what I am doing is not "correct", but an error condition or whatever
would be much better here than a crash.

Thanks.
