Talking about SMSC modules. Where would one start, writing a new one? Which source files have to be altered...
gw/smscconn.c: to add an entry for your new smsc module gwlib/cfg.def: if u need special config params for that connection
then u need to write your module. Start, mmm look at the smpp module or the emi2 module.
And what are the requirements that a module should have?
Well, it should meet the requirements of your upstream provider, it should meet the requirements as in smscconn_p.h and it should be nice and well behaved ;-)
Is there any documentation?
Start with smscconn_p.h
