For example, to set your modem to operate as a V.32bis modem, enter:
AT+MS = V32b,1,9600,14400[CR]
You can leave a parameter at its current value by leaving that parameter’s place blank and entering
a comma to separate the parameters or by entering a carriage return ([
CR
]) if it is the last
parameter.
For example, to change the selected modulation from the setting shown above
(
AT+MS=V32b,1,9600,14400
) to a Default mode of full V34, VFC, V32bis, V22bis, Bell 212,
and Bell 103, enter:
AT+MS=V34,,300,[CR]
Displaying Selected Values
You can use
AT+MS?
to display the values you selected with the
AT+MS
command. The modem
displays the selected values in the following order:
<mod>,<automode>,<min rate>,<max rate>
For example, if you enter
AT+MS?[CR]
,
your modem might display
+MS:
K56,1,300,56000,0,0
.
This display means that the values currently selected on your modem are V.34 with automode
enabled. The minimum rate is set at 300 bps, and the maximum rate is set at 56,000 bps.
