Siemens MC55 AT manual Atssda Set SMS Display Availability, Atssda=?, Atssda?, SSDAda, ATSSDA=da

13.23AT^SSDA Set SMS Display Availability

This command allows to notify the MC55 of its controlling application's capability to immediately display incoming SMS on a display.

If the application is able to display incoming short messages, a class 0 message shall be displayed immediately. However, if it does not, class 0 messages shall be treated as if no message class is determined (GSM 03.38[17]). The effect of this command if <da>=1 is to determine the behavior of parameter <mt> of AT+CNMI:

If <da>=1 and <mt>=1 incoming class 0 mesages need to be acknowledged with AT+CNMA (see also AT+CNMI and AT+CSMS)

If multiplex mode is enabled (AT+CMUX) and <da>=1 with <mt>=1 is set on any logical channel, all other chan- nels have to use <mt>=0.

Parameter Description

<da>(num)

Display Availability
0(&F)	Application is not able to display incoming short message
1	Application is able to display incoming short message

Note

•If the ME operates on different instances (MUX channels 1, 2, 3 or ASC0/ASC1) avoid different settings for routing and indicating short messages. 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.
