Emacs escaping getty

I create two virtual serials by socat -d -d pty,raw,echo=0 pty,raw,echo=0 in the specific case, I got /dev/pts/9 and /dev/pts/16 I then start screen on one side, in one X terminal, specifically gnome-terminal (for what it matters) screen /dev/pts/9 9600 vt52 and getty on the other side (from root), in another X terminal (again, gnome-terminal) getty pts/16 9600 vt52 I then login in the screen terminal. I can ls, etc. However, when I launch emacs (inside screen,thus NOT graphical) I get emacs's output on the getty's terminal, instead of inside screen's terminal. How is that possible? How can I fix that? I do not know if that's related, but when I login I get -bash: cannot set terminal process group (64718): Inappropriate ioctl for device -bash: no job control in this shell
