Hu? I never heared this and never experienced it either.
I'm using 19200 baud on a relative slow AT (8 MHz) all the
time and had never any problems. You have to use a terminal program
that causes the serial interface to generate interrupts whenever
a character arrives and installes his own interrupt handler for these.
I believe that you then can even run 19200 baud on an XT when you make
screen output fast enough (direct screen writes).
