- 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.
