近年来,随着计算机通讯技术的飞速发展,调制解调器的应用得到极大的普及,因此计算机通讯故障遇到的就越来越多,但由于许多计算机用户对调制解调器知识知之较少,在工作中一旦出现问题就束手无策,不能正确判断是通讯故障还是其它原因,给正常的工作带来不便。其实大多数计算机通讯故障是由于调制解调器及其RS-232C接口故障和一些通讯协议约定不当所造成的。下面给出国光2400PLUS调制解调器8个面板指示灯的正常工作状态及工作情况分析,其它品牌的大同小异。这些指示灯动态地反映着MODEM的工作是否正常。如果与正常状态显示不符则说明有故障。 In recent years, with the rapid development of computer communication technology, modem applications have gained tremendous popularity. Therefore, computer communication failures are encountered more and more. However, since many computer users have less knowledge about modems, If you have any problems, you can not judge whether the problem is due to a communication failure or other reasons, and bring inconvenience to normal work. In fact, most of the computer communication failure is due to the modem and its RS-232C interface failure and some communication protocols caused by improper agreement. The following gives Guoguang 2400PLUS modem 8 panel indicators of the normal working conditions and job analysis, other brands are more or less the same. These indicators dynamically reflect the MODEM work is normal. If it does not match the normal status, it means there is a fault.
