Actually, the 8250 (and its very similar successor, the 16450 used in
ATs) is made by National Semiconductor.  Intel makes a serial chip
called the 8251 which is quite different.  Documentation on the 8250
and 16450 can be found in IBM's various PC and AT Technical Reference
manuals, as well as other books about PC hardware.
