Chat Server
A simple server that distributes any incoming messages to all
connected clients. To use telnet to your device's IP address and type.
connected clients but the client the message comes from.
To use telnet to your device's IP address and type.
You can see the client's input in the serial monitor as well.
Using an Arduino Wiznet Ethernet shield.
