Subject: Re: Help needed with 8251 USART

I may be naive, but the best place to go to school on any USART is the
overlays for MODEM7 and its descendents.  Go through the documentation
and find one that uses the USART, and download that overlay.  If the overlay
is squeezed and you can't read it, I will download it, unsqueeze it and
mail it to you.
