public final class EchoUDPClient
extends DiscardUDPClient

The EchoUDPClient class is a UDP implementation of a client for the Echo protocol described in RFC 862. To use the class, just open a local UDP port with open and call send to send datagrams to the server, then call receive to receive echoes. After you're done echoing data, call close() to clean up properly.
