Parameters and Values
<pin> AT commands serial port interface hardware pin.
0 DCD (Data Carrier Detect).
1 CTS (Clear To Send).
2 RI (Ring Indicator).
3 DSR (Data Set Ready).
4 DTR (Data Terminal Ready). This is not an output pin: value is maintained only for
backward compatibility, but trying to set its state raises the result code “ERROR”
Not yet implemented.
5 RTS (Request To Send). This is not an output pin. The value is maintained only for
backward compatibility. Trying to set its state raises the result code “ERROR”
<state> State of AT commands serial port interface output hardware pins 0, 1, 2, 3 when
pin is in GPIO mode. See #V24CFG.
0 Low.
1 High.
Notes
 If <state> is omitted the command returns the actual state of the pin <pin>.
Battery and Charger Status #CBC
Execute command returns the current battery and charger state in the format:
#CBC: <ChargerState>,<BatteryVoltage>
where:
<ChargerState> Battery charger state.
0 Charger not connected.
1 Charger connected and charging.
2 Charger connected and charge completed.
<BatteryVoltage> Battery voltage in millivolt. This is the real battery voltage only if charger is not
connected. If the charger is connected this value depends on the charger voltage.
Test command returns the OK result code.
