Have you verified that the values that you get from the EQI
module (before they are written to the USART) are OK ?
Like writing them to some PORTx and verifying them
with a scope/meter or LEDs ?

The key here is to find you where the "garbage" pops
up first. My guess is that this is not an UART issue
at all, but that is has something with how you have setup
the QEI module (whatever *that* is, I've no idea...).

Exactly how do you *know* that "the QEI module can
function properly" ?? How is that verified ?
