reports or the final result code (e.g., CONNECT) is transmitted.
+MR=0
Enables the modulation report (default).
+MR=1
Disables the modulation report.
+MS=<carrier>,<automode>,<min_rate>,<max_rate>±Modulation
Selection
Use this command to set the modem±s modulation, the modulation±s
minimum and maximum transmission rate, and the status of automatic
modulation negotiation (automode). The <carrier>, <min_rate>, and
<max_rate> parameters define the modulation and its minimum and
maximum rates.
The <automode> parameter enables or disables automatic modulation
negotiation. If a subsequent
+MA
command is not provided, the automode
parameters are constrained by the modulation set by the <carrier> parameter.
The
+MA
command can further restrict the automatic modulation
negotiation settings but it cannot set a modulation that is higher than the
modulation set by the
+MS
command.
