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.
