Hi,

> communicate on is 500000 baud and it appears that data is being 

500kBps is quite a lot. Even with 115 kBps I loose a byte from time to
time without using hardware handshake. This results from interrupt
latency and the small FIFO buffer of the ATMega. You'll need to run a
blocking receiving routine to catch up all the data without any losts...

But I think 500Kbps (or even 1.5 MBps) continously streaming is far
beyond the capabilities of an ATMega together with NutOS.

What's Haralds opinion?

Regards,

Ole
