3. AUTO TCP/UDP CONNECTION
(Fargo Maestro 100 only)
The Auto TCP/UDP connection feature is defined for accessing serial devices over the Internet.
Fargo Maestro can be configured that after power up it will connect to a remote TCP/UDP socket
(client mode) or to wait for the TCP/UDP socket connection request from remote peer (server
mode).
If the socket connection is unsuccessful or disconnected it will repeat the connection request and
back to waiting stage. This make remote peer can access serial device connected to Fargo
Maestro.
