Modulation Selection +MS
Description: The extended-format compound parameter is used to control the manner of operation of the modulation
capabilities in the DCE.
Values: <carrier>
manufacturer specific
<automode>
0 Disabled
1 enabled with V.8 or V.32bis Annex where applicable
<min_rate> & <min_rx_rate>
set to 0 if unspecified
<max_rate> & <max_rx_rate>
set to 0 if unspecified
Syntax: Command syntax:
AT+MS=[<carrier>[,<automode>[,<min_rate>[,<max_rate>[,<min_rx_rate>
[,<max_rx_rate>]]]]]]
Command Possible Responses

Note: Display the range of parameters
OK
Note: Command is valid
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>[,…]]]]
Command Possible Responses
AT+MA?
Note: Display the parameter information.
+MA: V32, V32B
Note: Command is valid
AT+MA=?
Note: Display the range of parameters
+MA: (V32B,V32,V26B,V22B,V22,V21)
Note: Command is valid
AT+MA=V32
Note: Set to V32
OK
Note: Command is valid
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?
Note: Display the current setting.
+MR: 0
Note: Command is valid
AT+MR=?
Note: Display the range of setting.
+MR: (0,1)
Note: Command is valid
AT+MR=1
Note: Enable reporting.
OK
Note: Command is valid
