AT Commands
Configuration Commands
These commands recall various profiles for insertion into the active
profile, store the active profile and telephone numbers in nonvolatile
memory, and designate the powerup profile. Remote configuration is
discussed on page 5-41.
Configuration Profiles
Modem operations are controlled by option settings selected from
factory defaults stored in ROM, active settings stored in RAM, and
custom settings stored in nonvolatile memory. These three code storage
locations are called profiles.
Active Profile
The active profile holds the current option settings and is used by the
modem for all operations and functions. Any active profile option can
be changed to meet an immediate requirement. The active profile is
maintained in volatile memory referred to as S-registers.
Stored Profile
When an active configuration is established that meets all operating
requirements, it can be transferred to one of the stored profiles. Two
stored profiles are available for greater versatility.
If the active profile has been temporarily changed it can be reset to
either of the stored profiles with the Z command. The &Y command
selects one of the two stored profiles to be the powerup profile.
Factory Profile
The factory configurations are stored in ROM and cannot be changed by
the user; they can be transferred to the active profile and then modified
to fit a specific application if needed. The &F command recalls one of
the nine factory configurations.
