Re: Slightly unmatched UART frequencies

Error accumulates. 1% means that receiver accepts 9.9bit long farmes while
transmitter transmits 10.0 bit-long frames. After re-transmitting 100 bytes
(frames) we get 10-bit error. 10 bit is one byte, so 1-byte buffer is not
enaught. The longer the stream the lager the buffer required. Infinite
buffer is required for continous stream. As masters stated, UART was not
designed for this purpose.
