AT Commands Summary by Function
The reference tables are presented in strict ASCII alphabetical order (including prefixes). This format allows
quick look-up of each command to verify syntax, parameters, and behaviors. It does not lend itself to finding
whether or not the modem has a command to perform a particular service or setting.
The summary in this section organizes the commands into functional groups to allow you to more quickly locate a
desired command when the operation is known but the command is not.
