Data Mode AT COMMANDS
If the +MS=m parameters contain conflicting information like “+MS=V34,1,14400,0” with a DTE
data rate of 2400 bps, then the modem’s connection attempts always fail, and the modem reports a
“NO CARRIER” message. This happens because when the modem receives the +MS=m
command, the modem does not check for conflicts of valid parameter information.
shows the resulting connection data rate when using non-default values. Because of
impairments on the telephone line, the actual connection speeds may be lower than the speeds
defined in this table.
For V.92, V.90, and V.34 modulation, the modem can receive data at a different data rate than the
transmit data rate. All other modulation types besides V.23 and V.34 use the same data rate for the
transmitter and receiver. Use ATW3 to see the modem’s actual receive and transmit data rates (the
modem must be configured for ATV1 text response codes).

resulting connection rate when non-default values are used.
