 * The CharGenTCPClient class is a TCP implementation of a client for the
 * character generator protocol described in RFC 864.  It can also be
 * used for Systat (RFC 866), Quote of the Day (RFC 865), and netstat
 * (port 15).  All of these protocols involve connecting to the appropriate
 * port, and reading data from an input stream.  The chargen protocol
 * actually sends data until the receiving end closes the connection.  All
 * of the others send only a fixed amount of data and then close the
 * connection.
 * <p>
 * To use the CharGenTCPClient class, just establish a
 * connection with
 * {@link  connect }
 * and call {@link #getInputStream  getInputStream() } to access
 * the data.  Don't close the input stream when you're done with it.  Rather,
 * call {@link  disconnect }
 * to clean up properly.
 * <p>
