Sometime Today, Vijay Stevens assembled some asciibets to say:
What I did was to Change the ATDT string to ATX3 I may be worng. If so please tell me.
:)
Ok, some basics.
AT - the start of what are called AT commands D - dial command, followed by: T - tone dial P - pulse dial number - number to dial X - extended commands and many more
after AT, you can put as many commands as you want, and you must put all that you need.
generally, commands like X3, M1, etc are initialisation commands, and are specified in modem initialisation string. I don't know what software you are using, so can't tell you where to put it.
the DT command is required to dial the number, so don't take this out.
