Thanks for that, I can read the forth on Lubos site but struggle with 
the eastern european. Checkoslovakian ??

With the 485 I have always been a little concerned about the overhead of 
microcontrolers following a data stream of which only a fraction is 
addressed for the controler.

Reading through the Atmegas usarts there is an additional 9 bit mode 
that allows the usart to ignore traffic that is'nt addressed for the 
microcontroler in question. Good for reducing unnecesary interupts etc.

I think this could be useful.

Cheers
