Note: the command 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
- the GPRS has been activated with AT AT AT AT#GPRS #GPRS #GPRS #GPRS=1 =1 =1 =1
When a connection request comes on the input port, if the sender is not
filtered by the internal firewall (see command #FRWL), an unsolicited code
is reported:
+C
+C +C
+CONN FROM: <remote addr>
ONN FROM: <remote addr> ONN FROM: <remote addr>

Where:
<remote addr>
<remote addr> <remote addr> <remote addr> - host address of the remote machine that contacted the
