Abstract

본 발명은 데이타 통신 시스템에 있어서 본책의 입·출력 속도를 모뎀의 전송속에 맞춰 조정하는 방법을 개시한다. 컴퓨터 혹은 전전자 교환기와 입·출력을 담당하는 단말기 사이를 연결하는 전송로가 모뎀 혹은 DSU를 통하여 연결되어 있는 시스템에서 모뎀을 루프 백 모드로 제어하는 단계와 본체의 출력속도를 조정하는 단계와, 본체에서 특정글자를 출력하는 단계와, 출력한 글자와 이 글자가 루프되어 다시 본체로 입력된 글자를 비교하는 단계와, 본체의 특정글자를 출력하는 단계와, 출력한 글자와 루프되어 다시 본체로 입력되는 글자를 비교하는 단계와, 본체의 입·출력 속도가 정해지면 모뎀을 루프 백 모드에서 해제하는 단계를 포함하여 이루어지는 방법을 이용하여 사용자가 모뎀의 전송속도를 임의로 정하면 본체의 입·출력 속도가 모뎀의 전송속도에 맞게 자동으로 변경된다.The present invention discloses a method of adjusting the input / output speed of the present invention to a transmission speed of a modem in a data communication system. Controlling the modem to loop back mode and adjusting the output speed of the main body in a system in which a transmission path connecting a computer or an electronic switch and a terminal responsible for input / output is connected through a modem or a DSU; Outputting a specific character from the main body, comparing the output letter with a character that is looped back to the main body, outputting a specific character of the main body, looping with the outputted character and returning to the main body Using the method including comparing the input characters, and releasing the modem from the loop back mode when the input / output speed of the main body is determined, if the user arbitrarily determines the transmission speed of the modem, the input / output speed of the main body Will automatically change to match the modem's baud rate.
