Online State and Online Command State
If connection has not been established in ATC mode, the system is in online command
mode and permits the use of AT commands.
Once connection has been established, the system is in online state and does not
permit the use of AT commands. In order to use AT commands while TCP connection is
established, it is necessary to switch to online command state and then use AT
commands.
