Is that really true of modern hardware? The last time I looked at serial
port hardware, UARTs took a base clock rate and divided it sequentially
with flip-flops to get all the possible rates (they usually had some ugly
logic to generate 110). You were limited to the specific rates the
hardware gave you. Is that no longer the case?
