Siemens MC55 AT manual Atmoni responses, Mcc Mnc

•To some extent, the cell monitoring command AT^SMONC covers the same parameters. The receiving level, for example, can be queried with both commands. Yet the resulting values may be slightly different, even though obtained over a time period of a few seconds. This is quite normal and nothing to worry about, as the cell information is permanently updated.

•For compatibility with earlier products and to support legacy applications, any input character may be used to stop the output in certain cases (depending on the settings of AT+IPR and AT+CMUX).
