/*AT&T
AT&T If this option is enabled, when an intrupt key is pressed on the
AT&T keyboard (interupt, break, quit), all output in the tty driver
AT&T queue will be flushed, giving the effect of faster response to
AT&T the interrup, but causing curses to have the wrong idea of what
AT&T is on the screen.
AT&T Disabling the option prevents the flush.
AT&T The default for the option is inherited from the tty driver settings.
AT&T The window argument is ignored.
