*The +MS command was standardized by ITU-T recommendation V.250. However,
the standard command does not include the additional functionality provided by the
Bell212A and Bell103 values of the <carrier> parameter.
Automatic modulation negotiation is enabled or disabled by <automode>.
However, if a value is specified for the <max_rate> then, automatic rate selection
is disabled and the modem will attempt to connect at the specified rate.

The <max_rate> specifies the highest connections rate for the DCE.
