3. Status Control Commands
The AT Commands described in this chapter allow the external application to obtain various status information
from the AC75.

3.1 AT+CMER Mobile Equipment Event Reporting

This command controls details of the "+CIEV" URC presentation related to AT^SIND and AT+CIND. If registered
via these commands the URCs are sent whenever a value of the related indicator changes.
In addition, AT+CMER controls "^SLCC" URCs related to AT^SLCC. For details refer to Call Status Infor-
mation, AT^SLCC and AT^SCFG, parameter <sucs>.
The read command returns the URC presentation mode <mode> and among others, the indicator event reporting
status <ind>.
The write command enables and disables the presentation of "+CIEV: <indDescr>, <indValue>1[, <ind-
Value>2][, <indValue>[,...]]" URCs. <indDescr> refers to the name of a "+CIEV" indicator and <indValue>
is the new value of this indicator. After AT+CMER has been switched on, URCs for all registered indicators will be
issued. See examples provided in Section 3.2, AT+CIND and Section 3.3, AT^SIND.
