Comment 186 for bug 868034

Looking at Akila's MM log, I see two possible issues.

1. There may be an offending command here:

[1317801779.197484] [mm-at-serial-port.c:298] debug_log(): (ttyUSB0): --> 'AT+COPS=3,0;+COPS?<CR>'

After that command, there is no more answer from ttyUSB0.

2. Very close to that point there is an error on ttyUSB1 after the failed command:

[1317801779.161136] [mm-at-serial-port.c:298] debug_log(): (ttyUSB1): --> 'AT+CREG=2<CR>'

The response on ttyUSB1 is "+CME ERROR: 3". It might have messed up the modem somehow.
