Well the problem is that lots of SMS messages were being sent to that
number but not detected.. I'm wondering if there is maybe a different AT
command I should be issuing, as obviously the messages are no longer
being passed 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?
