Claims (1)

주장치부(10)와 다수개의 부가장치로 구성된 부가장치부(20)가 수신데이타 라인(31), 송신데이타 라인(32), 리궤스트 데이타 라인(33)으로 병렬 연결된 카폰시스템의 단말기 상호간 시리얼 통신방법에 있어서, 정보 전송 포멧 형태에 따라 정보를 편집하여 전송준비를 한 후 리궤스트 라인(33)의 상태를 체크하는 제1과정과, 상기 제1과정에서 리궤스트 라인(33)이 로우상태이면 상기 리궤스트 라인(33)을 하이 상태로 만들고 정보전송을 실행하는 제2과정과, 상기 제2과정에서 전송된 정보가 주장치부(10)에 정확하게 수신되었는가를 체크하는 제3과정과, 상기 제3과정에서 전송된 정보가 정확하게 수신되지 않았으면 주장치부(10)로 정보를 재전송하는 제4과정과, 상기 제3과정에서 주장치부(10)로 전송된 정보가 정확하게 수신되었으면 주장치부(10)로 전송종료 정보를 2번 연속하여 보내고 리궤스트 라인(33)을 로우상태로 유지하는 제5과정으로 이루어짐을 특징으로 하는 단말기 상호간의 시리얼 통신방법.Serial communication between the terminals of the car phone system in which the main unit 10 and the additional unit 20 composed of a plurality of additional devices are connected in parallel with the reception data line 31, the transmission data line 32, and the request data line 33. In the method, the first process of checking the state of the regress line 33 after the preparation for transmission by editing the information according to the information transmission format, and if the regress line 33 is low in the first process, A second step of making the request line 33 high and performing information transmission; a third step of checking whether the information transmitted in the second step is correctly received by the main unit 10; A fourth process of retransmitting the information to the main unit 10 if the information transmitted in step 3 is not received correctly; and a main unit 10 if the information transmitted to the main unit 10 is correctly received in the third process. Transfer sent to Two times in a row, having rigwe host terminal line serial communication method of one another, characterized by the yirueojim 33 in the fifth step of maintaining a low state. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
