Hello Vincent,

I think there is not much else than tcltk2. It is a complete implementation of DDE (client/server), so it should fit your needs. There are lots of examples on the man page. Please, if you think it could be helpful for other users, do submit examples. I think real-time acquisition of data through DDE under Windows would interest a couple of users (including myself).
Best,

Philippe Grosjean
