I have a problem with at2 driver when receiving mobile originated
messages. If there is lot of mobile originated messages coming in to at2
driver, then somehow the receiving of those mobile originated SM will
stuck the handling of SM messages. After all the at2 driver doesn't
detect any more the new mobile originated messages (no trace at all) but
however those will be saved into SIM memory. Outgoing SM works fine all
the time. When I restart the bearerbox and then I send a new mobile
originated SM to terminal, then it will get all the messages (old and
new ones) from the SIM memory. Following is a log file, which shows what
is happening:

The kannel version I'm using is the three weeks old snapshot from the
3glab site and the driver is 'at2'. This error is also happening with
the sourceforge version of the 'at' driver. Mobile terminal is siemens-tc35.
Current config for terminal is:
group = smsc
smsc =at2
modemtype = siemens-tc35
device = /dev/ttyS0
pin = 0000
smsc-id=SIEMENS
