The Amiga has probably the cruddiest UART that can still actually be called
a UART.

No FIFO.  No true RTS/CTS flow control.  (By true, I mean that the UART 
controls the lines in response to FIFO full/empty conditions).

But seriously, how much faster is my Sun4-100 expected to be over my 16-MHz
Amiga 3000?
