the 3% is specification-granted tollerance and it MUST be met by ANY UART. In reality the limit is much more loose and most of '51s working with 12MHZ crystals, generating constant 5% baudrate error work correctly and in many cases the tollerance is much wider. Of course if that's a "production" project you can't violate the specification tollerances, but if that's some hobby work, you can freely try whether it will work in your setup with baudrate errors as high as 5-8%. Some UARTs will tollerate even more. Some may fail a notch above the 3%. Yes, it's a hack. But if it works, well... it works :)
