I personally hate the ESC prefix. I think it was Terry who pointed out how they could be misinterpreted, and they're always a pain, slowing down your typing something awful. I'm a regular Emacs user, but in character mode I frequently prefer vi simply because of this factor. I think that the ESC prefix is the obvious solution for serial terminals, though: it's "intuitive" (i.e. well-known), and it's flexible enough to handle all the problems we've been talking about. I'll also allow sign bit set to mean the same thing. Greg
