Slight mod to the equation.... neither of the 56K modems can
actually run 56K.  53K is the legal "speed limit" due to FCC
regs...  that plus the "56K" standard is based on a series of assumtions,
such as only one AtoD conversion in the connection. Any more than that and
you have an expensive 33.6K modem...  :))
