Without error correction, however, transfer errors on the line are possible, which
means that the data protocol should be designed in a fail-safe way.
means that the data protocol should be designed in a fail-safe way.
Without error correction, data rates of up to 9,600 baud are possible for good
lines. Higher data rates are not recommended due to the many occurring errors.
For lower line quality, the error frequency will increase significantly according to
the baud rate, if no error correction is used.
