Establishing a data connection 
 
AT^SCFG=“AutoExec“,1,0,0,0,“ATD0123456789” 

 
When activating the DTR control line from the application, a data connection to the 
specified number (here 0123456789) is established. 
This is indicated at the serial interface: 
^SCFG: "AutoExec",1,0,0,0,"ATD0123456789" 

 
In this case already existing data connections are ignored, i.e. establishing alarm 
connections would fail in this situation. 
 
If you want to wait until an already existing data connection ends, you have to enter 
AT^SCFG=“AutoExec“,1,0,0,1,“ATD0123456789”

. 

 
If you want to terminate an existing data connection for the case of an alarm, the 
following must be entered: 
AT^SCFG=“AutoExec“,1,0,0,2,“ATD0123456789”

. 

 
The setting can be deactivated by entering the following: 
AT^SCFG=“AutoExec“,0,0,0 

 
The settings of this command are only stored with the command AT^SMSO. 
 
Note: With DTR activation it is basically also possible to establish a data connection using 
the setting AT%D ; the setting with AT^SCFG, however, offers more possibilities. For this 
reason we are not elaborating on AT%D within the framework of this document.
