TCP Client
In this mode, CSE-M73A functions as a TCP client. CSE-M73A sends request segments to
a remote host with information of [Peer Address] and [Peer Port]. Once a host is listening
and works correctly, the connection will be established. After then, CSE-M73A converts the
raw data from the serial port to TCP/IP data and sends them to the network and vice versa.
