1. If <max_rate> is within the rates supported by the selected modulation, the selected
rate
is that specified by <max_rate>. For example:
+MS=V32B,0,1200,4800 selects V.32 bis 4800 bps fixed rate.
2. 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. For
example:
+MS=10,0,2400,14400 selects V.32 bis 14400, 12000, 9600, 7200, or 4800 bps.
For <automode> = 1 (automode enabled, i.e., automatically selected speed and
modulation):
1. The modem connects at the highest possible rate in accordance with V.8 bis/V.8, or
V.32
bis Annex A if V.8 bis/V.8 is not supported by the remote modem.
2. 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 the selected modulation.
For example:
+MS=V32B,1,1200,14400 selects automoding down from V.32 bis 14400 bps.
<min_rate> and
<min_rx_rate> Optional numeric values which specify the lowest value at which the
modem may establish a connection. If unspecified (set to 0), they are determined by the
modulation means selected in the <carrier> and <automode> settings. Values for this
subparameter are decimal encoded, in units of bit/s. The value range is 75-56000 in the
following increments: 75, 300, 600, 1200, 2400, 4800,
7200, 9600, 12000, 14400, 16800, 19200, 21600, 24000, 26400, 28800, 31200, 33600,
32000,
34000, 36000, 38000, 40000, 42000, 44000, 46000, 48000, 50000, 52000, 54000, or
56000, as
permitted for the associated carrier. (Default = Lowest rate supported by the selected
carrier.)
<max_rate> and <max_rx_rate> Optional numeric values which specify the highest
value at which the modem may establish a connection. If unspecified, (set to 0) they are
determined by the modulation means selected in the <carrier> and <automode> settings
and by the current DTE-modem rate. Non-zero values for this subparameter are decimal
encoded, in units of bit/s. The value range is 75-56000 in the following increments: 75,
300, 600, 1200, 2400, 4800, 7200, 9600, 12000, 14400, 16800, 19200, 21600, 24000,
26400, 28800, 31200, 33600, 32000, 34000, 36000, 38000, 40000, 42000, 44000,
46000, 48000, 50000, 52000, 54000, or 56000, as permitted for the associated carrier.
(Default = Highest rate supported by the selected carrier.)
<min_rx_rate> and <max_rx_rate> May be used to condition distinct limits for the
receive direction as distinct from the transmit direction. For example, these can be used
to select either direction for asymmetric modulations like V.23 with constant carrier. The
value range is 75-56000 in the following increments: 75, 300, 600, 1200, 2400, 4800,
7200, 9600, 12000, 14400, 16800, 19200, 21600, 24000, 26400, 28800, 31200, 33600,
32000, 34000, 36000, 38000, 40000, 42000, 44000, 46000, 48000, 50000, 52000,
54000, or 56000, as permitted for the associated carrier. (Default = 0.)
Reporting Current or Selected Values
Command: +MS?
Response: +MS:
<carrier>,<automode>,<min_rate>,<max_rate>,<min_rx_rate>,<max_rx_rate>
Note: The current active settings are reported under control of the +MR parameter.
Example: +MS: K56FLEX,1,300,56000,0,0 For default values.
