SMS-gateway specific protocol update for CIMD2

Hello!
I needed to make changes for a project we are using Kannel as SMS
Gateway for and enclosed is the diff.  This update is made to enable
send of a truly empty message, used for location updating.  The update
is made from v1.2.1.

Just a quick question, has anyone experienced a problem of duplicated
received messages using CIMD2 gateway?
Best Regards,
SEG
