5.1.1.
Communication
In T2S mode, the EZL-410 functions as a server.
When a host connects to predefined local port, the EZL-410 accepts a TCP
connection. When the EZL-410 accepts TCP connection, then the TCP connection is
established. 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 to establish data communication. (Data coming to the serial port before TCP
connection is established will be ignored.)
5.1.2.
Connection Termination and Keep-Alive Function
If [Timeout] is set, EZL-410 terminates the connection if there is no data transmission
for pre-defined time ([Timeout] sec). If [Timeout] is set to 0, EZL-410 sends a Keep-
Alive packet every 10 seconds. If there is no response 4 consecutive times from the
foreign host, EZL-410 terminates the connection.
