I haven't looked at the tty code. However, under an almost straight BSD
4.3 system, output is not echoed or returned to the cooked buffer, and
it wouldn't matter anyway since all the applications use TIOCSETP.

In fact, under your BSD 4.3++ (ahem), output is not re-echoed, ^M is not
converted back to ^J, and line editing does not work upon the typeahead.
I just tried it today, so don't tell me things work.
