After re-checking, I confirm what you say. I must have mixed up client
and server when testing the first time. Which means: [iemnet/udpclient]
works as expected. After thinking about it, it is clear that the server
cannot know which clients are connected until they actually send
something, since there is no connection handshake involved.
