As I understand it, a baud is 'number of signal changes per
second'. If you use an encoding method which requires a signal
change for each bit, then 9600baud = 9600bps. Another encoding
scheme might only require 4800baud (4800 signal changes) to get
9600 bps across the wire.

In this case, it sounds like your modem uses a scheme which
somehow gets 4 bits across the wire per signal change, so
7Kbaud (7000 signal changes per second) gets across 56Kbps
(56000 bits per second).
