Maybe you are right that the EOF is needed only in certain modes.
I remember struggling to find a way to deal with the condition in
which the tty and Emacs are both waiting and the buffer is full.

    A related question is: why does child_setup_tty set ICANON even though
    the comments say "It should not echo or do line-editing, since that is done
    in Emacs".

Unforunately I don't remember the answer to that.
