FPU stands for Floating-Point Unit. It performs numerical operations
on "floating-point" numbers. Floating-point numbers are digital
representation of mathematical real numbers, but it is impossible to
represent an infinite precision in a finite number of bits, so you get
an error (small difference between the value what you should get and
the value what you really get, like 1/3 vs 0.333).

It doesn't use "mac modem software" to talk to the modem. It uses
its own. When you connect to the Internet via a modem, you usually
use pppd (which talks PPP) or slattach (which talks SLIP).
