Note: The resolution of the host name is done when opening the socket,
therefore if an invalid host name is given to the #SKTSET command, then
an error message will be issued.
Note: the DNS Query to be successful requests that:
- the GPRS context 1 is correctly set with +CGDCONT
- the authentication parameters are set (#USERID, #PASSW)
- the GPRS coverage is enough to permit a connection.
