 * 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.

* To use the CharGenTCPClient class, just establish a * connection with * connect * and call getInputStream() to access * the data. Don't close the input stream when you're done with it. Rather, * call disconnect * to clean up properly. *
