The 

 command controls the presentation of Indicator Event Reports related to various functions such

as battery charge level, signal quality, service availability, sound generation, indication of unread short mes-

sages, full SMS storage, call in progress or roaming activities. 

 has become outdated. Rather we recommend the more powerful 

 command which is

easier to use and provides additional indicators. All indicators provided by 

 can be handled with

 as well. 

 supports two ways to get the values related to indicators: 

• One approach is to query the current status of each indicator by using the read command 

?. It

returns the status no matter whether the indicator has been registered with the write command

=[

[,

[,...]]].

• The other way is an event-driven notification based on the "

" URCs. In this case, the ME will automat-

ically send a message to the application, whenever the value of an indicator changes. The application should

be designed to react adequately when receiving a URC. 

The presentation of these URCs depends on two settings: 
- The indicators must be registered with the write command 

=[

[,...]]]. When the

ME is switched on all of them are in registered mode. Any indicator can be excluded if deregistered with

=0. To register or deregister an indicator the 

 write command requires to type the value

=1 or 0 exactly at the position where the indicator is located in the list. This is not necessary with

 which allows to specify indicators by name. See examples below. 

- The presentation of the registered indicators must be enabled with 

Integer type value, which shall be in range of corresponding
