Command Reference

- 55

Table 3-104: +MR Commands

Table 3-105:

+MR Extended Syntax Commands

+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.

Result codes:

OK if <automode> = 0, 1 and <min_rate> = 0, 300—57333, and <max_rate> = 0,

300—57333, and carrier is equal to one of the entries in Table 3-106: Valid

<carrier> Values.

ERROR if <automode> does not equal 0, 1 or <min_rate> does not equal 0,

300—57333, or <max_rate> does not equal 0, 300—57333, or carrier is not equal

to one of the entries in Table 3-106: Valid <carrier> Values.

Command Function

+MR=0 Enables the modulation report (default).

+MR=1 Disables the modulation report.

Command Description

+MR=<value> Select or deselect transmission of the modulation result codes.

+MR? Display the current status of the modulation report result code.

+MR=? Display the supported parameter values for modulation rate reporting.
