Command: +MS Select Modulation
Values:
Default: n/a
Description: +MS= This extended-format command selects the modula-
tion, optionally enables or disables automode, and
optionally specifies the lowest and highest connec-
tion rates using one to four subparameters (client
modem) or five subparameters (server modem).
The command format is:
+M S=[,[][,[][,[
[,[]]]]]]
The modem can send a string of information to the DTE
consisting of selected options when AT+MS? is
entered. The following table is a display of subparam-
eter definitions:
