	What it will hopefully do, coupled with fixing the keyboard.device's
long disabled sections that Bryce found, is remove all the overrun errors
we get at higher baud rates (19.2KB+), and with a 68010+ remove the problem
of the video mode causing overruns at high baud rates due to the CPU not
being able to process the interrupt fast enough.
