Well, after some tests, seems that the exposed APP ports in this device
are like in any other Sierra device, with a limited AT command set, so
we cannot use them as primary port... Now I wonder if lacking a proper
primary AT port is a firmware/device bug or if they really did it on
purpose (e.g. so that only CnS can be used).
