In COD(Connect On Demand) mode, the ezTCP functions as a client.
When data of the pre-specified size [Event Byte] comes to the serial port, the ezTCP attempts a TCP connection to the TCP port [Peer Port] of the preset host IP [Peer IP Address]. If the remote host accepts the TCP connection, TCP connection will be established. Data coming to the serial port after connection establishment is TCP/IP-processed and transmitted to the remote host. And, data coming from the remote host is TCP/IP-processed and ransmitted to the serial port for data communication. If there is no data transmission during seconds [Timeout], the ezTCP will close TCP connection.
