4.1.3 TCP Client Mode Operations
The LS110 acts as a TCP client, and the default TCP state is [Closed] in this mode. The remote host
will be either Ethernet-Serial communication devices acting as a TCP server or a socket program
acting as a TCP server running on users’ PC.
1) Typical State Transition
[Closed] --> [Sync-Sent] --> [Established] --> [Data] --> [Closed]
At start-up, an initial TCP state is [Closed]. If there is any incoming data through the serial port, the
LS110 will try to connect to a user-defined remote host. Then, the state will be changed to [Sync-Sent],
