- The 'AF' part is just a newer model. The 'A' model will accomplish the
- same thing for you. Of course, if the chip isn't manufactured by National

- It's not the chip's fault; as far as I know, there's no way for software to
- determine the difference between a 16550A and 1655AF.

- I believe that National improved the design a couple of years ago and has
- been selling only AF chips since.
