115200 is certainly NOT the right value.  The UART is programmed with 
special values to produce 115200 baudrate, and none of these values has 
the value 115200.  (Actually, the higher the rate, the lower the values 
you program into the UART, IIRC.)

In the termios interface, the Bnnnnn macros are simply manifest 
constants, they are converted to real values by the termios functions.
