Thanks for your comment. I also think that it has to do with buffering, and in this case I have zero knowledge about the properties of the other process, except what I already said.

I also thought first that somehow EOF won't be recognized, so I explicitly sent a "Windows Textfile EOF" (Control-Z), but - as I already had expected - this had no effect. I think I will follow the solution suggested by BrowserUK. To be honest, I had hoped that I would find a solution which will then work on Unix too (although this is not required), but it seems that Windows and Unix are too different in this respect...
