    Makes unattended operation more challenging...
    Ever considered building a robot to press the button? :-)

    I haven't used soundmodem for a while, so apply grains of salt as required.
    A quick perusal of the kernel soundmodem code suggests
    that the output is held quiet when not transmitting,
    at least for half duplex, so consider making up a VOX circuit.
    This also gives you your serial port back.

    Whether this holds for the user version, or if it's relevant, I don't know.
    Thomas?

    Circuitry should be easy, depending on audio level and your radio setup.
