3.18 AT+CIND Indicator Control
Used to set the values of ME indicators. <ind> value 0 means that the
indicator is off (or in state which can be identified as “off” state), 1
means that indicator is on (or in a state which is more substantial than
“off” state), 2 is more substantial than 1, and so on. If the indicator is a
simple on/off style element, it has values 0 and 1. The number of
elements is ME specific. If the ME does not allow setting of indicators
or it is not currently reachable, +CME ERROR: <err> is returned. If a
certain indicator is not writable, it cannot be set. If the parameter is an
empty field, the indicator will keep the previous value.
Test command returns pairs, where string value <descr> is a maximum
16 character description of the indicator and compound value is the
allowed values for the indicator. If ME is not currently reachable,
+CME ERROR: <err> is returned (refer to GSM 07.07).
