    You can define VIDEO_CHAR() to do whatever makes sense for your
    hardware. The only problem with an 8 bit port is you cannot use both
    "screen" position and value to indicate where you are, you can only use
    a value. But the same idea holds, whatever works until the console can
    display output.
