<mode>
Mode of TCP operation. Default value is “S”.
“S” Server (Listening) mode. This configures Fargo Maestro to open a listening TCP
connection on the specified port . The TCP connection will be active upon getting socket
connection request from the allowed remote TCP peer (see <address>)
“C” Client (caller) mode. This configures Fargo Maestro to request opening  a TCP to the
server with the specified address  and port .

<address>
The address of the TCP 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 TCP 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.

<TCPTxDelay>
This parameter determines the time delay introduced before sending a TCP 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 TCP frame as soon as possible after the reception
of a single character value from the host.
The default value is 100.

This command controls the Maestro 100 to start UDPcket connection automatically.

Note :
- Before using AT+AUTOUDP TCP and GPRS settings MUST be setup properly using

AT+IPUDP and AT+IPGPRS command respectively.

- +AUTOUDP function is mutually exclusive with +AUTOTCP function; if +AUTOTCP is set to 1

already you will get ERROR on enabling AUTOUDP
