but it appears to have dumped into the debugger today for no apparent
reason.
The below looks like you ran a terminal application on the client end of
the serial console that generated a break signal, then initialized the
modem using an AT command string. I.e., you might want to set your
communication client to not generate a break signal and initialize the
modem... If that's not possible, try using ALT_BREAK_TO_DEBUGGER instead
of BREAK_TO_DEBUGGER in order to avoid accidental breaking to the
debugger.
