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.
