> 13.27 | AT^SSDA Set SMS Display Availability

> This command allows to notify the TC65 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[22]).
> The effect of this command if <da>=1 is to determine the behavior of parameter <mt> of AT+CNMI:
> If multiplex mode is enabled (AT+CMUX) and <da>=1 with <mt>=1 is set on any logical channel, all other channels have to use <mt>=0.

> • | 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.
