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?
