I have been going back and for between the UDP server code Kim pointed me toward and Hayoo for an hour. I can load it into GHCI, but I understand neither how it works nor how to use it. If I knew how to use it I could probably figure out a lot of how it works on my own. If I wanted to, say, send the message "test" to localhost port 9000, how would I do that?

Here's a fully working UDP echo server:

No special package needed, merely import the humble, dependable Network.Socket.
