After reading many posts about GPRS, I don't find the answer I am looking for.
I know that for making a GPRS conection I need the AT commands, OK.
But I don't have any idea how to make the PPP link,
Can someone explain what steps I can follow to complete the connection operation ?
and if is posible what I have to use (a program developed completely from me, the TAPI, ???),
because I am completely lost.
