[Hilo] Is it possible keep DCD signal in OFF(inactive) status when sending a SMS? Can <AT&C2> work for that?

Answer: No. Hilo respects TS 27.005 definition, so:

  • The DCD signal shall be in ON state while text is entered
  • The DCD signal shall be in ON state while PDU is given

AT&C0 can always keep DCD signal in ON(active) status.
AT7C2 is not supported.
