        The 8250 does not stop at 9600 baud;  the ROM BIOS (or disk-based
BIOS one of the two)  stops at 9600 baud.  You cannot do an MS-DOS
A>  MODE  COM1:19200,n,8,1   .

        The 8250 has a divisor word,  which is set to 000C (twelve) when
you set  MODE  COMx:9600,etc.  If you set that divisor to  1  then you
would be running at 115200 baud,  and your 8088 would probably not process
the interrupts fast enough to keep up.
