Hi,
 
Could some please tell me how the first field in the header of every PDU, the command_length, is handled in Kannel?
I can't find a reference to it anywhere. This field is not even in the smpp_pdu.def file.
 
Is it a case of just ignoring the first 4 octets of an incoming PDU and reading the length of the PDU off the conn interface?
If so, why?
 
How is this field added to outgoing PDU's in order to comply with the SMPP v3.4 spec? It doesnt seem (to me at least) to be done in the smpp_pdu_create function in smpp_pdu.c
 
Regards
Brendan.
