TCP Client
In this mode, CIE-H14A acts as a TCP client. CIE-H14A sends request segments to a
remote host with information of [Peer Address] and [Peer Port]. Under situation that the
TCP server works fine with the specific port, the connection will be established. After then,
CIE-H14A converts the raw data from the serial port to TCP/IP data and sends them to the
network and vice versa.
