Example : +MS=9,0,1200,4800 selects V.32
4800bps fixed rate.
b. If <max_rate> is greater than the
highest speed supported by the
modulation specified by <mod>, the
starting rate is the highest rate supported
by the selected modulation.
Example: +MS=9,0,2400,14400 selects
V.32 9600 or 4800bps.
c. To emulate N0S37=x command
sequence to select fixed mode operation,
specify the <max_rate> and <min_rate>
both to be the same requested speed, and
<mod> to be the modulation for that
speed.
Example: +MS=11,0,16800,16800 selects
V.34 16800bps fixed mode (no comparable
S37 command).
+MS=9,0,12000,12000 selects V.32
12000bps fixed mode (same as
N0S37=10).
For <automode> = 1 (automode enabled;
i.e., automatically selected speed and
modulation).
a. If <max_rate> is greater than the
highest rate supported by the modulation
specified by <mod>, the modem
automodes down from the highest rate of
selected modulation.
Example: +MS=10,1,1200,24000 selects
automoding down from V.32bis
14400bps.
b. To emulate N1S37=x sequence
command, specify the modulation and
the rate to start automoding down from
using <mod> and <max_rate>,
respectively. Set <min_rate> to 300 to
allow automoding all the way down to
V.21 300bps.
Example: +MS=11,1,300,16800 selects
automode starting at V.34 16800bps (no
comparable S37 command)
+MS=9,1,300,12000 selects automode
starting at V.32bis 12000bps (same as
N1S37=10).
3. <min_rate>= is an optional number
which specifies the lowest rate at
which the modem may establish a
connection. The value is decimal-coded
in units of bps, e.g., 2400 specifies the
lowest rate to be 2400bps. The default
is 300 for 300 bps.
4. <max_rate>= is an optional number
which specifies the highest rate at
which the modem may establish a
connection. The value is decimal-coded
in units of bps, e.g., 14400 specifies the
highest rate to be 14400bps. The default
is 28800 for 28800bps.
