Howto distinguish between a busy and a not available line by modem call
Posted by Udo Ornik on December 3rd, 2003


I like to call a phone number by modem and find out if the number is
available.
So far i get a busy answer string both if the line is busy or not available.

Any idea?

Best regards


Udo
