AT Command Set

6.38 AT^SSDA Set Display Availability

Use the AT^SSDA command to specify whether your TC35 / TC37 product is designed to provide a
display. If there is one available, AT^SSDA enables or disables the mobile station to present
incoming Class 0 short messages directly on the display. The command is not required for other
short message Classes.

defined profile.
Reference Note
Siemens If a mobile station is able to display short messages, class 0 messages shall be
displayed immediately. If the mobile station has no display, class 0 messages
shall be treated as though there was no message class.
Refer to GSM 03.38.
The setting of <da> influences the behaviour of the <mt> parameter in the
command AT+CNMI. This is the only effect of this command. If <da>=1 and
<mt>=1 or 3, then Class 0 short messages will be treated as if <da>=0 and
<mt>=2. For details on AT+CNMI refer to Chapter 5.10.
Multiplex protocol:
If using <da>=1 and <mt>=1 on one instance, all other instances have to use
<mt>=0.
