* cursor-off - Disables the VGA text mode cursor.
*
* This is an old tool that calls a special system call
* to change the VGA text-mode cursor position. The VGA
* terminal renders its own cursor in software, so we
* try to move the hardware cursor off screen so it doesn't
* interfere with the rest of the terminal and look weird.
