Well the problem is that lots of SMS messages were being sent to thatnumber but not detected.. I'm wondering if there is maybe a different ATcommand I should be issuing, as obviously the messages are no longer beingpassed through after the very start.

    Howdy All,

    I am having a problem where SMS's stop being received after a minute
    or two of inactivity.  Receiving the messages works fine immediately
    after startup but then nothing.

    This is using a Sierra Wireless 875 PCMCIA aircard, using the
    following config.  Log is attached below showing reception of one
    message, but then nothing even though the keep-alive messages are
    ACK'ing ok.

    group = smsc
    smsc = at
    modemtype = auto
    device=/dev/ttyUSB0
    my-number = 12063595733
    connect-allow-ip = 127.0.0.1
    keepalive=60
    log-level = 0

    I'm using a 60 second keepalive but that doesn't seem to be
    helping.  Any other ideas?
