M20 is an earlier, widely used SIEMENS GSM engine. The AT^M20 command
simply controls the behaviour of the ATD command during voice calls. Please
note that this command has no effect on any other differences between M20
and products based on x35/37 firmware.
OK
Parameters
<n> 0 Compatible to x35/37mobiles.
If this mode is active, TA returns OK right after attempting a
call.
1 Compatible to M20.
If the M20 mode is active, TA returns OK once the call is
successfully set up. Issuing any command before TA returns
OK will cancel the call setup.
