0 - TCP (factory default)
1 - UDP
<remote port> - remote host port to be opened
0..65535 - port number (factory default is 0)
<remote addr> - address of the remote host, string type. This parameter

Note: <closure type> parameter is valid only for TCP socket type, for UDP
sockets shall be left unused.
Note: <local port> parameter is valid only for UDP socket type, for TCP

- the GPRS context 1 is correctly set with +CGDCONT
- the authentication parameters are set (#USERID, #PASSW) the GPRS
