Thanks for your kind attention, but I don't think it's a matter of
buffering (I indeed tried playing with hSetBuffering with no results).
As I said I'm not even sure if what I intend to do can actually be
Basically I'd like to write the equivalent of "expect", which talks to
interactive programs (with the difference the mine is supposed to talk
to a program I wrote, so I don't need to embed a domain specific
language in it).
Since I don't know all this handle/channel/process interaction stuff
I'm leaning towards some other kind of server/client type of
interaction, probably with sockets...:-(
