MACRAW mode. W7100A can transmit and receive the data with others by ‘open’ the SOCKET.
The W7100A supports the independently and simultaneously usable 8 SOCKETS. In this section,
the communication method for each mode will be introduced.

After the W7100A initialization process, open the SOCKET to TCP or UDP or IPRAW or
The TCP is a connection-oriented protocol. The TCP make the connection SOCKET by using
Methods of making the connection to SOCKET are “TCP SERVER” and “TCP CLIENT”. It is
The “TCP SERVER” listens to the connect-request from the “TCP CLIENT”, and makes
The “TCP CLIENT” transmits the connect-request first to “TCP SERVER” to make the
