Automatic and self-recovery TCP/UDP
connection
The Auto TCP/UDP connection feature is defined for accessing serial devices over the Internet. Modem can be
configured to connect, after power up, 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 Maestro modem.
The socket can be set to be disconnected after a period of unconditional connection or zero data traffic.
