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. - *

- * 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. - *
