 The ModemConfigurationCommand message allows users to change certain aspects of modem operation on-the-fly (at runtime). The modem configuration settings are stored in flash memory and are untouched by the bootloader during a software update (assuming the correct cellular_c5 linker file is used during compilation of vi-firmware). Thus, new modem settings persistent across power cycles.
 
-The ModemConfigurationCommand message provides three sub-messages for particular groups of modem settings. These are NetworkOperatorSettings, NetworkDataSettings, and ServerConnectSettings. These configuration messages are described in great detail within the [c5_cellular_config](https://github.com/openxc/vi-firmware/docs/advanced/c5_cell_config.mkd) documentation.
