13.23 AT^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.

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.
