NOTE
If you are using AT commands, a period of time can exist in which
the contents of Active (Operating) and Active (Saved) differ. Once
you issue an AT&W0 (write) command, however, the two storage
areas are identical.
Figures 4-1 and 4-2 graphically display the interaction between the edit area and configuration
areas as viewed from the perspective of the DCP and the A
T command set.
