I don't like how IBM screwed interrupts architecture of IBM PC,
completely ignoring Intel's recommendation to assign hardware
interrupts to INT #32 and higher.
The unnecessary mess they created had negative effect for a long time,
15 years at least.
Also I am not sure that at time (1981) 8250 was the optimal choice for
UART chip.
