Serial Interface Control Commands

The command controls the behavior of the UE‟s DCD (data carrier detection) line.

3.1. AT&C Set DCD Function Mode - page 31

The commanddetermines how the UE responds if DTR line is changed from lowto highlevelduring data mode.

3.2. AT&D Set DTR Function Mode - page 31
