The external device determines whether the external device has recognized the portable terminal according to signals with a predetermined form, which have been output from the portable terminal regardless of the on/off state of the power source thereof, and outputs signals for a predetermined period of time according to a result of the determination. Thereafter, the portable terminal recognizes the external device according to the number or the form of signals input from the external device through a recognition node for a predetermined period of time. As a result, the portable terminal can recognize more various external devices, such as an external battery and a charging cradle which provides stereo sound, by using the recognition node of the portable terminal.
