    I’m using a GSM SocketModem with GPS and it’s not responding to any commands. Is there a master echo command that I could send it?

    I’m going to make a couple of assumptions here:

    1. GSM SocketModem means MTCDP-G2

    2. You’re using minicom to talk to /dev/ttyS1

    (You can use <ctrl>-a, <ctrl>-e to turn local echo on in minicom, meaning it show what you are typing. For a full list, use <ctrl>-a, <ctrl>-z)

    type ‘AT’ without the quotes and followed by a carriage return, and the modem should respond with ‘OK’ on the next line.
