Create and read SMS User Data Header

[StumpiDK]

Hi,

im (trying) to develop an application for sending sms messages, and it actualy works, width sms'es up to one message long.

I like to send (and recive) messages longer than one message and therefore i need to finde out how to create and read the header information of a SMS.

Because i dont know anything about sms headers than to set the UDHI bit, and that the header, for an example could look like this:

..............AA BB CC DD EE FF GG HH
SMS'es A:
Header 1: 05 00 .03 C8 02 01 8A
Header 2: 05 00 .03 C8 02 02 CA
SMS'es B
Header 1: 06 08 .04 00 26 04 01 C7
Header 2: 06 08 .04 00 26 04 02 65
Header 3: 06 08 .04 00 26 04 03 F4
Header 4: 06 08 .04 00 26 04 04 EE

of the context i concludet that the first two digits (AA) tells how many hex folowing. The digits EE & FF (in sms'es B digits FF& GG) must be the total numbers og messages, folowed by the current message id.
The digits BB, CC, DD (and EE) must be some kind of unik id for the SMS'es.

Am i rigt or wrong, and can anybody help?

regards
Christian
