Test command to be defined.

AT+CBC=??

Enhanced test command returns the complete range of values for
and :

+CBC: (0-3),(0-100)

Example

AT+CBC

+CBC: 0,75

+ CBC - Battery Charge

SELINT 2

AT+CBC

Execution command returns the current Battery Charge status in the format:

+CBC: ,

where:
- battery status
0 - ME is powered by the battery
1 - ME has a battery connected, and charger pin is being powered
2 - ME does not have a battery connected
3 - Recognized power fault, calls inhibited
- battery charge level
0 - battery is exhausted, or ME does not have a battery connected
25 - battery charge remained is estimated to be 25%
50 - battery charge remained is estimated to be 50%
75 - battery charge remained is estimated to be 75%
100 - battery is fully charged.

Note: =1 indicates that the battery charger supply is inserted and the
battery is being recharged if necessary with it. Supply for ME operations is
taken anyway from VBATT pins.

Note: without battery/power connected on VBATT pins or during a power
fault the unit is not working, therefore values =2 and =3 will
never appear.

AT+CBC=?

Test command returns parameter values supported as a compound value.

+CBC: (0-3),(0-100)

Note: although +CBC is an execution command, ETSI 07.07 requires the
