There is no general rule why the 8250 won't work on an OS/2 system.  If you
use the standard COM0x.SYS driver, the 8250 in fact very often WILL work.
The COM16550-drivers I mentioned before, are special designed for the
16450/16550 UARTs though.

But even if you use the standard COM0x.SYS driver, you MAY get problems
if you have the 8250 UART.  Sometimes it will malfunction, and sometimes
the driver will refuse to install at all.  There area lot of different
versions of the 8250 UART available, and some of them are buggy (don't
work with some special data formats, and some won't work with send data
IRQ).
