On a lot of the older chips with internal oscillators that is a valid statement. And I guess you could say that even on the new ones, when you consider the full temperature range, it's still a valid statement.

But, when you're sitting in a room at somewhere close to 25°C, the internal oscillator of the 18F4525 will be within +/- 1%, which should be fine for asynchronous comms. So it doesn't really account for you're problem.

Your register settings look good.

Are you using any @ __CONFIG lines? Or just the defaults for PBP with a 4525?
