"If the modem has to interrupt the CPU 1440 times a second, it certainly
eats up a lot of the time available for other things."
That's theory, that's not knowledge. After all if you assume that an
interrupt takes a 1000 instructions to process, then you are talking about
perhaps 5% of the CPU for handling the device. Who knows if the figure of
1000 is reasonable or not (it is ludicrously high but, these big operating
systems are in the ludicrousness budiness :-)
the point is that just assuming without measurement is entirely unconvincing,
it's no better than guessing.
