비동기 데이타 통신용 코드 변환 장치Code conversion device for asynchronous data communication

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 장치의 구성도.1 is a block diagram of an apparatus of the present invention.

Claims (1)

데이타 라인이 입력되는 라인 수신기(1)를 비동기 통신용 LSI(2)을 통하여 라인 구동기(3)에 연결하고, 스위치 셋팅 랫치(4), 처리기(5), ROM(6) 및 송수신용 버퍼(7)를 데이타 버스로 비동기 통신용 LSI(2)에 연결하되 ROM(6)내에는 1바이트 데이타를 수신하고 송수신 버퍼(7)에 수신 데이타를 기억하여 수신 데이타의 최상위 비트가 1인가를 검사하는 제1단계와, 최상위 비트가 1이 아니면 제1단계로 되돌아 가고 최상위 비트가 1이면 다음의 1바이트 데이타를 수신하고 송수신 버퍼(7)에 다음 한글 바이트를 기억시킨 다음 한글 조합형에서 한글 완성형으로 변환하는 스위치(SW1)가 온 되었는가를 검사하는 제2단계와, 스위치(SW1)가 온 되었으면 조합형에서 완성형 변환 루틴을 호출하고, 스위치(SW2)가 온 되지 않았으면 완성형에서 조합형으로 변환하는 스위치(SW2)가 온 되었는가를 검사하여 온 되었으면 완성형에서 조합형 변환 루틴을 호출하여 송수신 버퍼(7)에 변환된 코드값을 기록하는 제3단계와, 스위치(SW2)가 온 되지 않았으면 송수신 버퍼(7)내에 기억된 바이트를 차례로 전송하고 제1단계로 되돌아 가는 프로그램을 기억시켜 된 비동기 데이타 통신용 코드 변환 장치.The line receiver 1 into which the data line is input is connected to the line driver 3 through the LSI 2 for asynchronous communication, and the switch setting latch 4, the processor 5, the ROM 6 and the buffer for transmitting and receiving 7 Is connected to the LSI (2) for asynchronous communication via a data bus, but receives 1 byte of data in the ROM (6) and stores the received data in the transmit / receive buffer (7) to check whether the most significant bit of the received data is 1; The switch returns to the first step if the most significant bit is not 1, and if the most significant bit is 1, receives the next 1 byte data, stores the next Hangul byte in the transmit / receive buffer 7, and then converts the Hangul combination type to the Hangul completion type. A second step of checking whether (SW 1 ) is on, and if the switch (SW 1 ) is on, the combination type conversion routine is called from the combination type, and if the switch (SW 2 ) is not on, the switch is converted from completion type to the combination type ( SW 2 ) A third step of calling the combined conversion routine from the completed type to record the converted code value in the transmit / receive buffer 7 if it is turned on, and if the switch SW 2 is not turned on, in the transmit / receive buffer 7 A code conversion device for asynchronous data communication, in which a stored program is transferred sequentially and the program returned to the first step is stored. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
