ps. forgot to put up the log from today's crashed run; now here: http://christianjaeger.ch/scratch/bell_novatel/crashrun2/ Same thing as yesterday, the crash happens exactly at (or then within +-1 second of) the time nm sends AT+CSQ and then AT$CNTI=0. Going to try to look up what the latter command means. Maybe nm just shuts down the modem when it sees "No carrier", and the no carrier part is maybe a bug in the modem? Christian.
