In article <[e-mail]> you write:

> What's the difference between a 16550 UART and a 16550A UART? Thanks!

The difference is that the 16550 got bugs while the 16550A can be used
whithout problems even in fast serial communications. Other sources
say that only the 16550AFN from Nat Semi (i.e. not: second sources)
is really OK.

Best wishes
