 Yep.  smsc = http, send-url is as above.  MT-SMS comes in via kannel
 interface, is passed to the above URL, and then the URL passes the message
 in the SMSC-required format to the SMSC.

 The problem is with the UDH and TEXT of a binary message -- it is in ASCII
 control characters rather than the 000BFE12... format.  The SMSC-required
 format requires the 000bFE12 format, but I'm having trouble translating
 what kannel 1.3.1 hands me in the udh and text fields back to that format
 for sending.

 Why am I sending it in this manner rather than just passing it directly to
 the above URL correctly formatted?  I have a nice system which inserts a
 row in a mysql DB and then submits it to kannel, which in turn tracks the
 delivery.

 I could take kannel out of the loop, but that would double my efforts, so
 I'm trying to make this work.
