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 Fargo Maestro 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 Fargo Maestro to request opening a UDP to the
server with the specified address and port .
<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 the address is set to
“255.255.255.255” the modem will accept request from ANY address.
<UDPTxDelay>
This parameter determines the time delay introduced before sending a UDP frame that has not
been entirely filled with user data. The timer is entered in milliseconds and it should be noted
that a value of ‘0’ initiates the sending of a UDP frame as soon as possible after the reception
of a single character value from the host.
The default value is 100.
