Send UDP may be used to test UDP ports, in order to test if your datagram/UDP application works well, you'll need to send packets to it and test if it receives and read the packets well, the best solution for you is to use sendudp, if you ever used telnet to test your stream ports/TCP ports then you'll be familiar with sendudp, sendudp is an OpenSource tool you can edit it, customize it or just use it! sendudp is very simple to use even simpler that telnet, to use it you have to be familiar with the destination IP address, the IP could be v4 or v6, the PORT and you must define a message to test, here is an example:
sendudp -d 196.44.87.65:3877 -m "Test message."
Or
sendudp -d example.com:3877 -m "Test message."
while {-d} stands for destination and port, and {-m} stands for the message to send, enjoy using sendudp and I hope it saved you time from writing your own UDP tester.

I am sorry that the author has spent a plenty of time for reinventing the wheel. There is more powerful console tool which does the same and much more -- NetCat. It could be used for the same purpose this way: $ echo -n <message> | nc -uo <host> <port> Moreover, it can listen too: $ while true; do nc -lou <listen_port> < /dev/null; echo; done

I would recommend it, telnet is for TCP testing and sendudp is for UDP testing, no need to reinvent the wheel just use sendudp.
