Title: Telephone receipt alarm method using personal computer
Inventor: YUK SEUNG JONG
IPC: H04B1/40
Filed: 2002-08-28
Abstract: PURPOSE: A method for alarming call reception using a PC is provided to enable a PC receiving a call reception alarming signal from a terminal to display a call receiving message of preset contents on a monitor screen, thereby visually alarming call reception through the PC monitor. CONSTITUTION: If a communication cable is inserted into a socket of a terminal, the terminal recognizes the inserted communication cable and automatically converts into a non-sound mode(S101,S102). In the no-sound mode, the terminal outputs telephone reception displaying/telephone reception alarming signals through a socket terminal by a terminal indicator(S103). If the terminal receives a call while being automatically converted into the no-sound mode, the terminal generates the telephone reception alarming signal and transmits the generated telephone reception alarming signal to a PC through the inserted communication cable(S104,S105). A preset program of the PC senses that the telephone reception alarming signal is received, and outputs a telephone reception message on a monitor screen(S106).
