protocol to establish the connection before data communication, but UDP just processes the
data communication without connection establishment.
The Network mode of WIZ110SR can be divided into TCP Server, TCP Client and Mixed
mode according to the connection establishing method. At the TCP server mode, WIZ110SR
operates as server on the process of connection, and waits for the connection trial from the
client. WIZ110SR operates as client at the TCP Client mode on the process of connection,
and tries to connect to the server’s IP and Port. Mixed modes supports both of Server and
Client. The communication process of each mode is as below.
