How do I add a SAC (Security Access Code) in the sending software?
In order to add the SAC, you simply put your phone number (where the Stick is) into your sending modem software just like you always do, except at the end of the phone number you add three commas (commas represent a half second pause in computer language) and then the SAC (security access code). You can change the SAC to whatever you want up to 4 digits with the Stick.
