Description
The set command is used to specify the service or service preference that the MT will use to send MO SMS messages.
The read command returns the currently selected service or service preference.
The test command is used for requesting information on the currently available services and service preferences.
Defined Values
<service>: a numeric parameter which indicates the service or service preference to be used
0 Packet Domain
1 circuit switched
2 Packet Domain preferred (use circuit switched if GPRS not available)
3 circuit switched preferred (use Packet Domain if circuit switched not available)
Other values are reserved and will result in an ERROR response to the set command.
Implementation
Optional.
10.2 Modem compatibility commands
This subclause describes how existing AT commands, designed for use with a modem, may be used to control a Packet
Domain MT. This is to provide backwards compatibility with existing communications software. For new applications
it is recommended that the Packet Domain-specific commands, described in previous subclauses, be used.
10.2.1 MT originated PDP context activation
In this mode of operation, the MT behaves like an originating modem and accepts the normal V.250 commands
associated with placing and clearing a call. If Packet Domain-specific configuration commands are required, they may
be sent to the MT as part of the modem initialization commands.
