Re: Turning off automatic screen clanking

[Andries.Brouwer@cwi.nl]

    Yes. This is f*ing absurb. A default that kills the screen and the
    requirement to send some @!_$%!@$ sequences to turn it off. This
    is absolute crap, absolutely positively, with no possible justification
    whatsoever. If I made an ioctl, it will probably be rejected.........

What language. What about the below (not compiled, not tested)?
