Chapter 3
The modems store the register contents in the RAM. These register
settings are not available after modem deactivation. For further utilization
of these register settings they must be stored in the modems (nonvolatile)
EEPROM using the command AT&W(n)! The settings can be activated
later with the ATZ(n) command or by deactivating and restarting the
modem.
ATS? Register Display
With the ATS? command you can display all current register settings.
ATS(n)? Read Register (n)
The modems read and display the register content of the register (n).
Please refer to the chapter “Register Description“ for a complete listing
of all valid modem registers.
ATZ(n) Load User Setting (n)
The modems initiate a reset and then recall one of the user settings
specified with n = 0...2 from the EEPROM.
AT&F(n) Load Basic Setting
The AT&F command restores the factory default register settings that are
stored in the ROM. Only basic setting 8 may be overwritten and
corresponds to user setting 2.
After typing AT&F(n) the modems transfer these values to the RAM for
further processing.
AT&W(n) Save User Setting
The AT&W(n) command stores user defined settings in the modem's
nonvolatile memory (EEPROM). You can save individual profiles generated
with the ATS command for further utilization.
