- MSD, which ships with recent versions of Windows and MS_DOS, will tell you
- whether you have a FIFO (in which case it reports that the UART is a 16550AF)
- or not (in which case it reports that the UART is an 8250)... but you can't
- use it inside DOS boxes created by Windows, OS/2, XENIX/UNIX, etc. because it
- would then be reporting only on the virtual UARTs, not the real hardware.
