Serial Port
8.1
Introduction
CIE-M10 provides RS232↔TCP/IP conversion function along with input/output port monitor and
control function. Using this function, existing serial devices may be easily connected to the TCP/IP
network. Also, TCP server, TCP client, AT command emulation, UDP, and many other devices are
supported to provide various applications to the users.
8.2
Serial Communication Mode
CIE-M10 has 5 serial communication modes. The following chart is a brief explanation for each
communication mode

TCP Server
T2S is the mode that CIE-M10‟s serial port operates as a server.
When TCP connection comes through previously designated [Local Port] from remote host, CIE-
M10 will accept TCP connection. When CIE-M10 accepts the connection, TCP connection is
established. After establishing connection, data that comes through serial port will be sent to the
remote host after TCP/IP process, and TCP/IP data that comes from the remote host will be sent
to the serial port after TCP/IP process to establish data communication.
