Argh! Both "bus" and "line". The 16450A is capable of 500K, using
an 8 MHz baud clock. I don't think the original 8250 could go that
high. Bus timing is faster too.
Finding an original 8250(A) datasheet is a little daunting, however.
NS has lumped the 16450 and 8250 as one part now.
Even more interesting is the list of "personality" bugs between the
various NS parts and competing vendors.

They're all pin-compatible. The 16450
supports higher line speeds;
the 16550 has the 16-byte FIFO.
How much higher line speeds? Higher than 115200?
