Command Reference

- 54

ERROR if <carrier x> does not equal V90, V34, V32T, V32B, V32, V22B, V22,

Bell212A, V23C, V21, Bell103 or <carrier x> is greater than the carrier set by the

+MS command.

Table 3-103: +MA Extended Syntax Commands

+MR=<value>—Modulation Reporting Control

Use this command to enable or disable modulation report result codes. When the

modulation report is enabled, the DCE transmits the +MRR: <rate>, <rx_rate> and

the +MCR:<carrier> intermediate result codes to the DTE. The <carrier> reported

is the current modulation, for example, V.34. The <rate> reported is the transmit

rate in bits per second or is zero if negotiation fails. The <rx_rate> is the receive

channel rate and is only reported when different receive and transmit rates have

negotiated.

The intermediate result codes are transmitted after the modulation and the rate

have been determined and before any error control or data compression reports

or the final result code (e.g., CONNECT) is transmitted.

Result codes:

OK if <value> = 0, 1.

ERROR if <value> does not equal 0, 1.

Command Description

+MA=<carrier 1> Defines automode modulation list.

+MA? Displays the current automode modulation list.

+MA=? Displays the all available modulations.
