In TCP Server(TCP to Serial) mode, the ezTCP functions as a server.
When a TCP connection comes from a remote host to the predefined local port, the ezTCP accepts a TCP connection.
After connection is established, TCP/IP processing is performed on the data coming to the serial port, which is then transmitted to the remote host. And the TCP/IP data coming from the remote host is TCP/IP-processed and transmitted to the serial port for data communication. (Data coming to the serial port before TCP connection is established will be ignored.) If there is no data transmission during seconds [Timeout], the ezTCP will close TCP connection.
In Server(T2S)mode, the ezTCP functions as a server. Therefore, T2S mode cannot be used in a dynamic IP environment (DHCP, PPPoE, etc.)
