The real-time control unit 20 outputs to the personal computer 10, and generates a call signal or a response signal during transmission and reception, and modulates the analog-type data of the HDLC protocol by inputting the HDLC protocol data of the lab ratio controller 30. The modem 60 which demodulates the data and the control signal of the personal computer 10 are inputted to the modem 60. And a parallel input / output circuit unit 70 for controlling the lap ratio control unit 30 and the interrupt logic circuit 90, and detecting a ring signal upon reception, and inputting a call signal, a voice answer signal, and analog data of the modem 60. And amplification unit 80 for transmitting and receiving analog data transmitted through a public telephone communication network to or received from an analog teletex to the amplification modem 60, a wrap ratio interrupt signal of the wrap ratio controller 30, and the real-time interrupt. A teletex system having an interrupt logic circuit 90 for inputting a signal and the ring interrupt signal to a synthesized personal computer, wherein the state data of the modem 60 is input through the parallel input / output circuitry 70 to provide a modem ( 60) to check if it is hooked-on by hooking off modem 60 and performing a dial tone while performing a necessary task using a real-time interrupt on hook-on. Performs the necessary steps when the modem 60 of the first step is not in the hook-on state. The second step returns to the first step when a real-time interrupt is generated, and the dial tone in the second step. If a real-time interrupt is applied while processing the necessary work, the third step returns to the first step, and if the dial tone is generated in the second step, the necessary work is performed using the real-time interrupt and the busy tone is generated. A fourth step of searching for whether or not the second step is performed; and performing a necessary work process when the busy tone is not generated in the fourth step; and a fifth step of returning to the first step when a real-time interrupt is generated; and the busy tone in the fourth step If a real-time interrupt occurs, the sixth step of searching whether the answerton is input, and the answerton is not input in the sixth step. When the real-time interrupt occurs, the seventh step is returned to the first step, and when the anthonone is input in the sixth step, it performs the necessary work. Modem connection method of 8-step Teletex system. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
