I think the docs say it's cleared by default. Anyway, I tried both. So, I'm very puzzled that Fosc seems to be 1 MHz. > At 8MHz, the best baud rate accuracy you can get is -3.5% on 2x operaion, > which is very marginal to say the least.

I'll look for a more accurate speed, or try Joerg's suggestion to adjust the internal oscillator. -- Rick _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
