I think "z" should interrupt *any* transfer/negotiating
and switch immediately to listening-to-user mode,
so DOS user could press any keys... As it is on Unix.

I mean you should not abort program via ^C if you encounter any problem
with particular link (according to your words), but press "z"
and go another link... Or you mean the other,
smth like ^Z on Unix - not stop transfer, but suspend?
