Chapter 10 – +M Prefix Commands

CDMA 1xEV-D0 AT Commands Reference Guide (Document S000482B) 42

Chapter 10 – +M Prefix

Commands

+MA= Modulation Auto Mode

Syntax: AT+MA=<str>

AT+MA? (Queries the settings)

Description: Sets the additional modulations that the Base Station may use to connect with the

destination modem in Auto Mode operation. This is used for originating and answering

operations on data calls and is additional to the modulation setting using the +MS

(Modulation Selection) command.

The default setting is null.

For details on parameters and use, see IS-131.

+MR= Modulation Reporting

Syntax: AT+MR=<n>

AT+MR? (Queries the settings)

Description: Enables or disables the extended intermediate result codes for +MCR:<carrier> and

+MRR:<rate>[,rx_rate] from the IWF to the modem. For details on the intermediate result

codes possible, see IS-131.

To query the IWF for confirmation that the command is supported, use +GCAP (Get

Capabilities). The +MS result must be in that response.

If reporting is enabled, the intermediate result is sent when modulation has been

determined and before error control or data compression are negotiated. This is before the

final result code (e.g. CONNECT) is sent.

Value Meaning

0 Disables reporting of modulation connection. Default.

1 Enables reporting.

+MS= Modulation Selection

Syntax: AT+MS=<parms>

AT+MS? (Queries the settings)

Description: Controls the manner and operation of the modulation capabilities in the IWF. To query the

IWF for confirmation that the command is supported, use +GCAP (Get Capabilities). The

+MS result must be in that response.

The default setting is null.

For details on parameters and use, see IS-131.
