Hello. I tested the sms_handler_demo.py from your examples directory. In one of my computers it works perfectly fine, but in another, I have the following problem:

Initializing modem...
INFO: Connecting to modem on port /dev/ttyUSB2 at 115200bps
Traceback (most recent call last):
  File "sms_handler_demo.py", line 40, in <module>
    main()

IOError: [Errno 32] Broken pipe

Have you guys encountered that problem before? I have no idea what it is. I can access the modem with picocom -b 115200 -f n -p n -d 8 -r /dev/ttyUSB2 with no problem.

I found my answer here. My pip installed pyserial==3.4, I downgraded it to pyserial==2.6 and it is now working fine.
