Hmm, I have a patch somewhere to allow setting the sending port
directly, Iʼll see if I can find it and resurrect it.
Having said that, this sounds like it might be a bug (although I
haven't checked if the emacs code supports sending from a datagram
server like this). Could you open a bug with M-x report-emacs-bug with
your emacs version, and sample code?
