10.1.9&D, Circuit 108 Behavior
This command determines how the Module responds when the DTR (Data Terminal Ready) status is
changed from ON to OFF during the online data state. The DTR is an input line that indicates that the
terminal is ready.
The DTR line must be active (low) in order for the Module to recognize the terminal. This signal is raised
by the terminal when a process activates the serial port. If the DTR is not used by the application, it should
connect this line to ground (DTR active). The default value is active (low).
In case of local link during initial PPP retries, DTR change will be ignored.
