Use TAPI (Telephony API).  Specifically, see the lineMonitorDigits() and lineGatherDigits() functions.  Check the online help of your compiler for more details on TAPI.

Thank You.. Alexo I have already knew about the TAPI but the problem is I don't know how to use the TAPI's functions and it's reserved keywords on how to get a specific tone or digit inresponse to the tone. But I really don't know how to see the on-line help of my compiler.. cause I couln't find anything relating to TAPI. I really appreciate you have answered. Thank you very much.

If you're using MSVC, put the cursor on "lineMonitorDigits" and hit F1.
