Really good documented. Sure. Thanks for that big explanation.
As i said in the project web page, "interface between IP services and GSM messaging", so, i thought that a gateway was a good definition. Anyway, i didn't knew about gateway as a deprecated term. Well, i think it does not matter a lot. About bridging, i do not worry about ethernet or gsm stuff, so i think it has less of bridge and more of "protocol converter" or gateway. I use other lowlevel programs to use them. Alamin uses TCP in one side and SMS at the other. Bye.
