Just think of trying to read a serial port RX pin signal and try to time that using that method in software under windows.
That's exactly what I could do under DOS 10 years ago to dsample synchronous bitstreams from a shortwave receiver. I could simply point the interrupt vector to my own handler , do my thing, and _then_ let DOS do it's thing. 200 accurately timed interrupts/sec? No problem on a..... 16 (sixteen) MHz system.
Even Windows Vista on a quad CPU 3GHz system can't do this today.
