8 years ago I think you should have to use /dev/ttyUSB0 instead of /dev/ttyUSB2. If no other serial device is connected to your system, AFAIK, /dev/ttyUSB0 port is the main command channel and the /dev/ttyUSB2 port is the notification channel. You can watch notifications /dev/ttyUSB2 with simple screen command screen /dev/ttyUSB0 115200
I have Huawei E173 modem and when running identify-modem.py i have the output:
root@abudhabi:/home/jtardin/Documents/python-gsmmodem/tools# ./identify-modem.py -b 115200 /dev/ttyUSB2 args: Namespace(baud='115200', debug=False, pin=None, port='/dev/ttyUSB2') Connecting to GSM modem on /dev/ttyUSB2... Error: SIM card PIN required. Please specify a PIN with the -p argument.
This SIM don't have PIN enabled. I enable the PIN via smartphone and have the output now:
root@abudhabi:/home/jtardin/Documents/python-gsmmodem/tools# ./identify-modem.py -b 115200 /dev/ttyUSB2 -p 1010 args: Namespace(baud='115200', debug=False, pin='1010', port='/dev/ttyUSB2') Connecting to GSM modem on /dev/ttyUSB2...

Any idea?
Thanks.
