Note : possible argument
Defined Values:
<port>
The port number to be used for the UDP socket connection. Default value is 0. Valid range is 0 to 65535.
<mode>
Mode of UDP operation. Default value is “S”.
“S” Server (Listening) mode. This configures Maestro 100 2G to open a listening UDP connection on the specified
<port> . The UDP connection will be active upon getting socket connection request from the allowed remote UDP peer
(see <address>)
“C” Client (caller) mode. This configures Maestro 100 2G to request opening a UDP connection to the server with the
specified <address> and <port> .
Note: This parameter is used by Auto UDP connection (see Chapter 4) only.
<address>
The address of the UDP server (or host). Default value is empty. Legal values could be 32-bit in dotted-decimal notation
(i.e. xxx.xxx.xxx.xxx) or alphanumeric ASCII test string up to 120 characters (only if DNS is available on the GPRS
network)
Note: In “Server” (Listening) mode the modem will only accept UDP connection request for the caller with address
specified in the <address> field. Yet if it is set to “255.255.255.255” the modem will accept request from ANY address.
