High baud-rates, particularly if U2Xn = 1 in the USART, tend to get pretty cranky about mismatch.

| Feb 19, 2014 at 6:44 | comment | added | jippie | @FakeName At least one board on my desk here has increased BER when I push serial speed. I usually use 9600, that is more than enough for most applications and is robust. | |
| Feb 19, 2014 at 6:40 | comment | added | Connor Wolf | I really, REALLY doubt any of the boards out there have layout issues severe enough to prevent a 2 Mhz signal from working fine. 2 Mhz isn't exactly high frequency. | |
