57600 baud rate inaccuracy in arduino uno

spycatcher2k:
Try it as it is, I've interfaced with a lot of equipment at 57600 BAUD with no issues.

I can't try it as is because it's not good enough for my needs.
Have you ever sniffed your sent data?
As I said, if I set it as 57600, I get about 59000 which is not good, the PC can't "see" the arduino.
