Title: how to monitor phone call progress? Post by: gabriel on September 20, 2011, 04:11:37 16:11 hello:
I'm using my modem to call some numbers, by opening the corresponding serial port then sending the ATDT<number> command, it works fine. But now I want to know if there is already a dial tone or not, and if after dialing the line is busy, ringing, not answering etc.....in plain C language preferably (just to avoid TAPI using). How that? I know there is a status register that I should read, but I didn't found adequate documentation about that. any help is appreciated. thanks in advance Title: Re: how to monitor phone call progress?
