> 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 Information, 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[, <indValue>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.

> Parameter Description

> <mode>(num)

> 0(&F)
> Discard "+CIEV" and "^SLCC" URCs.
> 1
> Discard "+CIEV" and "^SLCC" URCs when TA-TE link is reserved, e.g. in online data mode. Otherwise they are forwarded directly to the TE.
> 2
> Buffer "+CIEV" and "^SLCC" URCs in the TA while TA-TE link is reserved, e.g. in online data mode, and flush them to the TE afterwards. Otherwise they are forwarded directly to the TE.
> 3
> Forward "+CIEV" and "^SLCC" URCs directly to the TE. If TC65 is in online data mode, URCs are signaled via sending BREAK and stored in a buffer. Once it is back in command mode e.g. after +++ was entered, all URCs stored in the buffer will be output.

> <keyp>(num)

> 0(&F)
> Keypad event reporting is not supported by TC65.

> <disp>(num)

> 0(&F)
> Display event reporting is not supported by TC65.

> <ind>(num)

> 0(&F)
> Disable indicator event reporting.
> 2
> Enable indicator event reporting.

> <bfr>(num)

> 0(&F)
> TA buffer of URCs defined within this command is cleared when <mode> 1..3 is entered.

> <indDescr>(str)

> Name of indicator; for a list of all supported indicators please refer to AT+CIND and AT^SIND.

> <indValue>(num)

> Value of indicator; for a list of all values for the supported indicators please refer to AT+CIND and AT^SIND.
> Notes

> • | If the ME operates on different instances (MUX channels 1, 2, 3 or ASC0/ASC1) avoid different settings for routing and indicating SMS. For example, if messages shall be routed directly to one instance of the TE (set with AT+CNMI, AT^SSDA), it is not possible to activate the presentation of URCs with AT+CMER or AT+CNMI on another instance. Any attempt to activate settings that conflict with existing settings on another interface, will result in CME ERROR, or accordingly CMS ERROR.

> • | It is recommended that priority be given to AT+CMER=<mode> 2 or 3. Otherwise, if <mode> equals 1, URCs will be discarded in case of long running AT commands or an active data connectiion.
