The 8250 is pretty much a brain damaged chip from what I hear. I'm not
sure about the 8530, but the NS16550AF or AFN are pin compatible
replacement Uart's that will handle the high speeds. When I picked up
my USR Hst 1441 modem (14,400 bps connects) I had to get a NS16550AFN
to replace my 8250. The 8250 could not handle the speeds above 9600.
Hope this helps.
Jim.
