I dont understand why it does not connect. Can someone show me what i do wrong?
Solved this problem.
I can't send data it keeps telling me requested service option not subscribed or operation not allowed.

Hello,
You are trying to establish a dialup PPP connection.
For that you need some PPP protocol implementation.
After the CONNECT your application should do PPP negotiation. In other case the connection is disconnected after some time and you only see some unreadable signs on the terminal which are in fact PPP frames.
