공중전화 통신망을 통해 정보를 상호교환하는 통신장치의 화상정보 통신방법에 있어서, 링신호가 검출되거나 송신요구가 입력되는가 검사하는 제1과정과, 상기 제1과정에서 송신요구신호 입력시 훅크-호프하고 다이얼톤을 발생하여 상대국을 호출하는 제2과정과, 상기 제2과정수행 후 호출된 상대국의 능력 및 기능을 알아보고 필터특성을 시험하여 송신가능성을 검사하는 제3과정과, 상기 제3과정에서 송신가능할시 호프관 변조된 후 압축저장된 문서화일을 1라인에 해당하는 양만큼씩 데이터를 독출한 다음 송신용 버퍼에 소정라인에 해당하는 저장용량이 있는가 검사하여 저장용량이 되면 상기 1라인 데이터의 첫머리에 EOL 데이터와 필데이터를 부가하여 송신용버퍼에 마지막 라인데이터까지 순차적으로 삽입송출하는 제4과정과, 상기 제4과정에서 마지막라인의 데이터를 송출했을시 EOP데이터를 송출한 다음 수신완료신호가 입력되는가 검사하는 제5과정과, 상기 제5과정에서 수신완료신호 입력시 선로단락신호를 송출한 다음 훅크-온하여 문서화일송신을 종료하는 제6과정과, 상기 제1과정에서 링신호검출시 수신가능상태인가 검사하여 수신가능 상태가 될시 훅크-오프하는 제7과정과, 상기 제7과정 수행 후 자신의 능력 및 기능을 상대국으로 송출하고 상대국이 요구하는 필터특성으로 자신의 필터특성을 조절함으로써 수신가능성을 검사하는 제8과정과, 상기 제8과정에서 수신가능할시 소정 시간동안에 EOL데이터가 입력되는가 검사하는 제9과정과, 상기 제9과정에서 EOL데이터 입력될시 최초의 EOL입력인가 검사하여 최초의 EOL일시 상기 제9과정으로 되돌아가는 제10과정과, 상기 제10과정에서 최초의 EOL입력이 아닐시 수신데이터중 1라인의 데이터를 추출하여 필데이터를 제거한 다음 수신화일에 저장하는 제11과정과, 상기 제11과정수행 수 EOP데이터가 입력되는가 검사하여 입력되지 않을시 상기 제9과정으로 되돌아가는 제12과정과, 상기 제12과정에서 EOP데이터가 입력될시 수신완료신호를 송출한 다음 선로단락신호가 입력되면 훅크-온하여 수신작동을 종료하는 제13과정과, 상기 제3과정에서 송신 불가능하거나 제5과정에서 수신완료신호가 입력되지 않은 경우 또는 제8과정에서 수신불가능하거나 제9과정에서 소정시간동안 EOL데이터가 검출되지 않을 경우 혹은 제13과정에서 선로단락신호가 입력되지 않을시 화일에 에러표시를 한 다음 훅크-온하여 이상 종료하는 제14과정으로 이루어짐을 특징으로 하는 컴퓨터상에서의 팩시밀리 프로토콜 구현방법.An image information communication method of a communication apparatus for exchanging information through a public telephone communication network, the method comprising: a first step of checking whether a ring signal is detected or a transmission request is input, and a hook-hop when the transmission request signal is input in the first step; A second process of calling a counterpart station by generating a dial tone, a third process of checking the capability and function of the called party after performing the second process, and testing a filter characteristic to check the transmittance; When transmission is possible, the data is read out by the amount corresponding to one line after the modulation of the HOPE tube is compressed, and the storage buffer corresponding to the predetermined line is checked in the transmission buffer. In the fourth process of adding the EOL data and the fill data at the beginning and inserting and sending sequentially to the last line data to the transmission buffer, and in the fourth process A fifth step of checking whether the reception completion signal is input after transmitting the EOP data when the data of the last line is transmitted; and sending a line short signal when the reception completion signal is input in the fifth step, and then hooking on the document file A sixth step of terminating the transmission, a seventh step of hooking-off when the ring signal is detected in the first step by checking whether or not it is in a receivable state, and performing a hook-off when performing the seventh step; Process 8 for checking receptionability by sending a signal to the other station and adjusting its filter characteristic with the filter characteristic requested by the other station, and a ninth process for checking whether EOL data is input for a predetermined time when it is receivable in step 8 above. And a tenth step of returning to the ninth step of the first EOL date and time by checking whether the first EOL is input when the EOL data is input in the ninth step, and the first in the tenth step. The eleventh step of extracting the data of one line from the received data and removing the fill data when the EOL data is not inputted and storing the received data in the received file; A twelfth step of returning to the ninth step; a thirteenth step of transmitting a reception completion signal when the EOP data is input in the twelfth step and then hooking-on to terminate the reception operation when the line short signal is input; In the case where transmission is impossible in step 3 or when the reception completion signal is not input in step 5, in the case where reception is not possible in step 8, or when EOL data is not detected for a predetermined time in step 9, or when the line short signal is input in step 13 Implement the facsimile protocol on the computer, characterized in that the fourteenth step of displaying an error on the file and then hook-on and terminate abnormally Way. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
