robtillaart,
Yes, I see that now. I did get 230400 to work, had data bits set incorrectly to 7 in the terminal. If I keep the speeds listed on the mega 328 datasheet for 16mhz, it works well, as you stated. I tried pushing it to 2mbs using the code you posted(see below). I didn't do any error checking, but it seemed to work fine. By the way, if anybody is interested, the speeds listed in the datasheet for 16mhz are 230400/250000/500000/1000000. Also it doesn't have it listed, but indicates 0% error up to 2mbs using u2xn=1.
Thanks for the help!
