Just do a web search on POSIX and TIOCSWINSZ.

And besides, that's irrelevant, especially since there are way too much
cases where we simply won't do the right thing (monitors lying about
their modes or incorrectly detected for example). There is a reason why
most OSes have this dialog asking you to confirm a resolution change and
click OK... It's fine with scaled flat panels to scale to pretty much
anything, but other cases are a bit more dodgy.

Anyway, the point is, such an option has NOTHING to do in the fbcon
layer unless we have fully implemented & properly working monitor
detection, which we are only starting to have and only in some drivers.

stty has its pros, such as allowing a user to at least set the video resolution
without being root.

And, of course, its cons, such as crashing the machine simply by using stty,
iff fbdev cannot handle these mode requests properly.
