+MS Modulation Method
The +MS command sets the modulation method for the modem.
+MS=Modu, Auto, MinSend, MaxSend, MinRec, MaxRec
Example:
AT+MS=V34,1,9600,33600,9600,33600
Preferably, V.34 modulation should be used here. If V.34 is not possible, another
modulation type is used (automatic adjustment of the modulation type). To send and
receive, a minimum of 9600 bps and a maximum of 33600 bps should be used.
6.3 S Registers
Your modem has 211 registers (S0 through S210). These registers influence the operating
characteristics of the modem, send you information via your modem, and enable you to
test your modem. The values of certain registers can be modified using specific
commands. If you use a command to modify a register value, this command remains active
until you switch off or reset your modem. Your modem then reverts back to the operating
characteristics stored in its permanent memory.
Reading a Register Value
Use the Sr? command to read the current value of a register:
r = Register number (0 through 210)
Your modem displays a three-digit decimal value for the register.
Modifying a Register Value
Use the Sr=n command to modify the current value of a register:
r = Register number (0 through 210)
n = New value
Modu= Modulation method (for possible values, see Table 6-1 on page 6-17).
Auto=0
Auto=1 Only use specified modulation type.
Automatic adjustment of the modulation type.
MinSend= Lowest baud rate for sending data (see Table 6-1).
MaxSend= Highest baud rate for sending data (see Table 6-1).
MinRec= Lowest baud rate for receiving data (see Table 6-1).
MaxRec= Highest baud rate for receiving data (see Table 6-1).
