I was contacted yesterday regarding the posibility that the FIFO in 
the 16550AN chips does not work correctly.  I phoned Richard Tuck at
National Semiconductor (800 272-9959) and he didn't know but said he
would research it and get back to me.  He was not optimitic about 
finding any information.  I did try 2 of the chips in a serial card
which I am using with a 28.8 K modem, no problems yet.  I ran 
Microsoft's MSD program which identified these chips as the 16550AF
version.  So that's all I know.  I can't guarantee them to work in
your application.  If you need a lot of them I recommend that you buy
one as a sample first.  I have so many of these I won't run out and
there's more where these came from.

Regards to all.
