- from what I read in the data sheets, that can probably be said for the
- 8250A vs the 16450, but not for the plain old 8250. of course, good
- luck getting UART identifying software to know the difference....from
- the programs I've seen, a visual of the chip is the only truly reliable
- way to know what you've got.
-
- see my previous post for more details, but there also seems to be a
- very substantial difference between the clones and the real chips from
- National Semiconductor (is this *REALLY* news to anyone?.....), so it
- is quite possible that every person in this discussion could be
- right, wrong, and somewhere in between, depending on which vendor's
- chip each person is using.
-
- type at y'all later.
