    Perhaps. Terminal modes & speeds & special lines and so on set on the
    tty side can be seen on the pty side, although I think the pty is not
    notified immediately so it has to poll if it wants to detect terminal
    programs sending a BREAK signal and things like that.

    I had a look at this about a year ago. I remember that a couple of
    small changes to the pty/tty layer would have been very handy to improve
    the quality of serial port emulation, and that might be the thing to do.
