The Socket TCP sample application contacts a listener program (a java program...included) with two processes, both of which are writing data.
The Socket MII sample shows how to write and read the MII by toggling the state of an ethernet LED.
The Socket PING sample shows how to use the socket library ping() function.
The Socket UDP sample shows how to use the UDP functions for transmitting datagrams.
