public class DiscardTCPClient
extends SocketClient

The DiscardTCPClient class is a TCP implementation of a client for the Discard protocol described in RFC 863. To use the class, merely establish a connection with connect and call getOutputStream() to retrieve the discard output stream. Don't close the output stream when you're done writing to it. Rather, call disconnect to clean up properly.
