I already replied to this with a trivial patch.  In addition to
proxying chars in/out, it should also handle SIGWINCH and set
the pty size accordingly.

No framebuffer will work here, framebuffer is not a pty or tty.
But anything like a screen editor (vi/nano/etc), screen(1) (which
is actually quite useful) and anything as simple as that -- I see
no reason why to restrict this.

Thanks!
