Execute command
ATD <number>
Starts a call to the phone number given as parameter.
Parameter: <number> - phone number to be dialled
Note: The call is a data call or voice call depending on +FCLASS setting. If AT+FCLASS=8
command was issued before calling then the call will be done as a voice call, instead if
AT+FCLASS=0 command was issued the call will be a data one. The default value of
+FCLASS is 0 hence calls are by default data ones.
The numbers accepted are 0-9 and *,#,”A”, ”B”, ”C”, ”D”,”+”.
For backwards compatibility with landline modems modifiers “T”, ”P”, ”R”, ”,”, ”W”, “!”,
“@” are accepted but have no effect.
