- Remember we're not talking about a real-time OS here, either. Even
- with the 16550's FIFO the response time might be slow enough that
- you'd be dropping bytes all over the place.
-
- In other words, I'd be extremely surprised to see anything faster than
- 38.4K actually work under Linux or any Unix running on an i[34]86. On
- a loaded-down system, no way. Remember, the serial buffers are sort
- of small, too. It might be nice to be able to re-size them, or simply
- re-compile the kernel to default to larger ones. (Maybe you can do
- this and I simply haven't looked...)
