13.27 AT^SSDA Set SMS Display Availability
Description: This command allows to notify the Multi-Tech wireless modem 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 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.
Test Command Syntax: AT^SSDA=?
Response: ^SSDA:list of supported <da>s
OK
Read Command Syntax: AT^SSDA?
The read command returns ME’s current capability setting.
Response: ^SSDA:<da>
OK
Write Command Syntax: AT^SSDA=<da>
Response: OK
Parameter Description:
<da>
Display Availability
0 Application is not able to display incoming short message. Default.
1 Application is able to display incoming short message.
Note: If the ME operates on different instances (MUX channels 1, 2, 3 or ASC0) 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.
