&Cn | Data Carrier Detect (DCD) Control |

&C1: DCD turns on when the remote modem’s carrier signal is detected, and off when the carrier signal is not detected (default).
&Dn | DTR Control |
This command interprets how the modem responds to the state of the DTR signal and changes to the DTR signal.
&D0: Ignore. The modem ignores the true status of DTR and treats it as always on. This should only be used if your computer does not provide DTR to the modem.
