You want to connect to a end-user telephone using a modem ? Or maybe you want
to connect to another modem ! Anyway...
I'm using the CreateFile / WriteFile / ReadFile API to communicate using
my modem.
You use CreateFile("COM2",......); // Open you modem COM port
Then, use the WriteFile command to send ->AT Commands<- to your modem.
By exemple you could send the string "ATDT 888-8888" to your modem. Don't
forget that a modem has 2 modes. Read your modem userguide for more info.
Once connected, you send you data normally using the WriteFile API (ReadFile
can be used also !)
If you need more help, contact me
Good luck
