Problem decoding MMS notification message

Hi all,

	I have a GSM modem and have clients who want to send MMS to me. My 
understanding was that I got a notification message telling me where the 
MMS was at which point I would then make the connection and grab it. 
Sure enough I get the notification message but then I get a seg fault.

The problems seem to start well before the seg fault when in smsc_at.c 
we decode the message. What comes out seems to be rubbish. Is the 
notification message in a completely different format or am I just being 
stupid somehow?
