- * A class derived from TFTPRequestPacket definiing a TFTP read request
- * packet type.
- * <p>
- * Details regarding the TFTP protocol and the format of TFTP packets can
- * be found in RFC 783. But the point of these classes is to keep you
- * from having to worry about the internals. Additionally, only very
- * few people should have to care about any of the TFTPPacket classes
- * or derived classes. Almost all users should only be concerned with the
- * <a href="org.apache.commons.net.tftp.TFTPClient.html#_top_">TFTPClient</a> class
- * <a href="org.apache.commons.net.tftp.TFTPClient.html#receiveFile">receiveFile()</a>
- * and
