sim-buffering is for MO retrival from the modem, ie, periodically,
kannel will query the modem to see if there is a MO stored in modem.
This is the "oposte" from CNMI that will tell the modem to pass the MO
to kannel.
Your original problem was with MT. CMGS was telling the modem to
receive an MT, and it was responding to that with a busy error, that
could come from the modem processing an MO...
