ES-Registers
The configuration of the DART is accessible to the Mobile Application Subsystem (MAS) as a set of parameters known as Status (S)-Registers. Some registers can be updated directly with AT commands, others are read-only. The set of registers and modem options (also set with AT commands) is known as the configuration profile. At least three distinct profiles are present in the DART, including:
∙Active Profile - Set of register values and options actually used as the current operational parameters of the modem. Registers can be queried individually with the ATSn? command, or modified using the ATSn= command (where n = the S-Register number). The entire profile, registers and options can be viewed with the AT&V command
∙Saved Profile - Used at power-up to establish the power-on configuration state. It is created by the write profile (AT&W) command, that copies the current active profile into the profile save area. The saved profile is preserved across cold starts or power-cycles. The saved profile can be recopied over the active profile at any time with the soft reset (ATZ) command. Some CDPD modems (but not the DART) can have more than one saved profile available for use
∙Factory Profile - An embedded permanent profile that cannot be modified from the factory default setting. The factory profile can be copied into the active profile with the load defaults (AT&F) command.
Register display formats
The S-Registers can be displayed in groupings by use of the AT&V commands: AT&V for S-Registers 0 through 99, and AT&V+ for S-Registers 100 through 126. The format of the data displayed by these two AT&V commands is different. In addition, the format of the data displayed by the ATSn? command is also different in many cases, particularly for registers above 100. These variations are summarized below.
