Command Reference

Table 3-101: +IPR Commands

Table 3-102: +IPR Extended Syntax Commands

+MA=<carrier 1>,<carrier 2>, ...—Modulation Automode Control

Use this parameter to define a list of modulations that the 56K Softmodem may

use to connect with a remote modem for answering or originating automode

(automatic modulation negotiation) data calls. The list acts as an extension to the

modulation specified by the +MS=<carrier> command. The modulation identified

by <carrier> in the +MS command limits the values in the +MA carrier list.

Modulations which exceed the rate set by the +MS command (see Table 3-108:

Valid <max_rate> Range. Valid <max rate> for each <carrier> for more

information), generate an ERROR result code and are not implemented by the

56K Softmodem. <carrier> values omitted from the list are not available for

automode negotiation and are not used in automode negotiation even when the

modem is capable of generating the modulation.

Result codes:

OK if <carrier x> = V90, V34, V32T, V32B, V32, V22B, V22, Bell212A, V23C, V21,

Bell103 and <carrier x> is less than the carrier set by the +MS command.
