팩시밀리 통신의 팩스 인터페이스 유니트에서 코맨드 수신방법에 있어서, 인터럽트가 발생되면 INTC가 인터럽트 벡터 어드레스를 실어줌에 의해 해당 회선의 관리 테이블의 베이스 어드레스를 정하는 제1과정과, AL레지스터의 값이 0FFH가 아니고 BX+SYNC_FLG가 가리키는 주소의 값이 1이 아니면 CL레지스터가 7EH일 경우 플래그를 카운트하여 어드레스 필드가 나올때까지 계속 체크하는 제2과정과, 상기 BX+SYNC_FLG 가리키는 주소의 값이 1이면 CL 레지스터가 7EH가 아니고 CH레지스터 값이 8일 경우 데이터를 저장하고 플래그가 디텍트될 때까지 체크하는 제3과정과, CL레지스터 값이 7EH로 플래그가 체크되면 버퍼카운터를 증가하여 AL레지스터 값이 5보다 클 경우 이벤트를 발생하는 제4과정으로 이루어짐을 특징으로 하는 다중 FAX통신을 위한 T.30프로토콜 코맨드 수신방법.In the method of receiving a command in the fax interface unit of facsimile communication, the first process of determining the base address of the management table of the line by the INTC carrying an interrupt vector address when an interrupt occurs, and the value of the AL register is not 0FFH. If the value of the address indicated by BX + SYNC_FLG is not 1, the second step of counting a flag and continuing checking until the address field appears when the CL register is 7EH; and if the value of the address indicated by BX + SYNC_FLG is 1, the CL register is 7EH. If the CH register value is 8 and the CH register value is 8, save the data and check it until the flag is detected. If the CL register value is 7EH, check the flag counter and increase the buffer counter to increase the AL register value. Number of T.30 protocol commands for multi-fax communication, characterized by the fourth process of generating an event Way. 팩시밀리 통신의 팩스 인터페이스 유니트에서 코맨드 분석방법에 있어서, 이벤트를 수신하게 되면 수신 데이터에서 1이 5개 후에 들어오는 0을 딜리트하는 수신 딜리트 과정과, CRC체크를 하여 CRC에러가 발생하면 재전송 코맨드를 송신하고 CRC에러가 없으면 코맨드를 분석 처리하는 코맨드 분석과정으로 이루어짐을 특징으로 하는 다중 FAX 통신을 위한 T.30 프로토콜 코맨드 분석방법.In the command analysis method of the fax interface unit of facsimile communication, when an event is received, a reception deciding process for deciding incoming zeros after 1 to 5 in the received data and a retransmission command when a CRC error occurs by performing a CRC check T.30 protocol command analysis method for multiple FAX communication, characterized in that the command analysis process for analyzing the command if there is no transmission and CRC error. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
