Chapter 17 – Extended AT Commands in IS707.3

Modulation Automode Control +MA

Description: The extended-format compound parameter is a list of modulations that the DCE may use to connect with the remote DCE in automode operation, for answering or originating data calls.

Syntax:

Command syntax: AT+MA=[<carrier>[,<carrier>[,<carrier>[,…]]]]

Modulation Reporting Control +MR

Description: The extended-format numeric parameter controls whether the extended-format +MCR:<carrier> and +MRR:<rate> intermediate result codes are transmitted from the IWF to the mobile station.

Values:

<Val>

 

 

0: Disables reporting of modulation connection

 

1: Enables reporting of modulation connection (+MCR and +MRR are transmitted)

Syntax:

Command syntax: AT+MR=[<Val>]

 

 

Command

Possible Responses

 

AT+MR?

+MR: 0

 

Note: Display the current setting.

Note: Command is valid

 

AT+MR=?

+MR: (0,1)

 

Note: Display the range of setting.

Note: Command is valid

 

AT+MR=1

OK

 

Note: Enable reporting.

Note: Command is valid

V.18 Reporting Control +MV18R

Description: The extended-format numeric parameter controls whether the extended-format +MV18R: result code is transmitted from the IWF to the mobile station.

Values:

<Val>

 

 

0: Disables reporting of V.18 connection

 

1: Enables reporting of V.18 connection

Syntax:

Command syntax: AT+MV18R=[<Val>]
