-/***
- * The CharGenUDPClient class is a UDP 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 sending a datagram to the
- * appropriate port, and reading data contained in one or more reply
- * datagrams. The chargen and quote of the day protocols only send
- * one reply datagram containing 512 bytes or less of data. The other
- * protocols may reply with more than one datagram, in which case you
- * must wait for a timeout to determine that all reply datagrams have
- * been sent.
- * <p>
- * To use the CharGenUDPClient class, just open a local UDP port
- * with {@link org.apache.commons.net.DatagramSocketClient#open open }
- * and call {@link #send send } to send the datagram that will
- * initiate the data reply. For chargen or quote of the day, just
- * call {@link #receive receive }, and you're done. For netstat and
- * systat, call receive in a while loop, and catch a SocketException and
- * InterruptedIOException to detect a timeout (don't forget to set the
- * timeout duration beforehand). Don't forget to call
- * {@link org.apache.commons.net.DatagramSocketClient#close close() }
- * to clean up properly.
