 Regarding that it has a 3 byte fifo one should think it would be worth a
closer look at, so to say: Well I've missed one interrupt... hmmm... never
mind, next time, I'll fetch two chars. You could start calculating a
probability for missing three interrupts after another...

 But then: What's about the MSTE problems with it? Have heard about them,
but nothing concrete. And what about the falcon? Have only heard it doesn't
use a MFP for serial communication. Don't know what it uses.

 Looks like there'll never be a kernel with new device drivers, because
you would have to write three of them for all existing hardware... :-(
