It generates a passable number, but the tend to stay in step TX/RX. Heavy networking is better for randomness (or sending form another host). When testing serial drivers I also run a strobing carrier signal into the serial drivers to check for races. In the 1.2 era this was quite effective but 2.0.x seems to have to got the races out
