the controller 216 detects the outgoing mode controls the modem 23 to process the received dial information and controls the rf unit 21 to convert the dial signal to a rf signal and transmit the rf signal through an antenna if a response signal is generated in the other side the controller 216 detects the response signal thereafter the controller 216 performs a communication function by forming a voice call path by using the audio processing unit 25 in an incoming mode the controller 216 detects signals by using the modem 23 that the wireless terminal is in the incoming mode and generates a ring signal by using the audio processing unit 25 when the user responds to the incoming call the controller 216 detects the response and performs the communication function by forming a voice call path by using the audio processing unit 25 in the outgoing mode and the incoming mode the voice communication has been described as an example however a data communication function to transmit receive packet data and image data may be performed besides the voice communication when a short message service is performed in an idle mode the controller 216 displays character data processed by the modem 23 on the display unit 80 an operation of inputting data by using the jog key 90 in the wireless terminal according to an exemplary embodiment of the.
