Wavecom 2406B-IP Modem

Dear Reader

Please share with me the sequence of AT commands from power on to connectivity, which performs the following:

(1) Activate GPRS session (I have no problem to make it).

(2) Open PPP with user name and password.

(3) Open TCP/IP with IP address and port number.

Each AT# command sent to the modem, results in error message.

Many thanks - Antoni A. Urban
