Abstract
A method for transferring dual tone multifrequency (DTMF) signals in real time in a computer communications system for performing a telephone call via a modem. In the method, virtual connection with the modem is performed before a user inputs a connection number, wherein the modem is regarded as the external device to be connected. Then, when the virtual connection is achieved, a dual tone multifrequency (DTMF) signal corresponding to a number is transferred in real time through the modem whenever the user inputs the connection numbers one by one.
