一、“AT,oK”:运行中并不真正OK——互联网用户使用中会碰到的问题 有的用户反映互联网连起来并不总是那么顺手:有时很不容易接通;拨通上网电话后网络提示信息无法显示;有的连上Web站点后传输速度极慢,差错极多;有时还出现死机,但是经检查调制解调器与计算机的连接没有问题,应用软件安装也是正确的,输入“AT”命令,屏幕上响应“OK”。如果排除了电话线路质量不佳。所访问的站点路由繁忙等外界原因,情况仍然未有改善,原因大多产生在调制解调器及相关软件的参数设置上。 “AT,OK”只是表示调制解调器与计算机的电气连接基本正确,调制解调器与计算机之间能进行信息交流。在此基础上还应进行一系列参数的设置,才能确保系统在进行互联网通信时TCP/IP协议的正确执行,以达到满意的上网效果。 Hayes标准AT命令集是调制解调器通信接口的工业标准。AT命令集可以用来配置调制解调器与它所连接的计算
First, “AT, oK”: not really running OK - Internet users will encounter problems encountered Some users reflect the Internet is not always so easy to connect: Sometimes it is not easy to connect; dial-up Internet phone After the network prompt message can not be displayed; Some even connected to the Web site transmission speed is extremely slow, the error is very large; sometimes there is a crash, but check the modem and the computer connection is no problem, the application software installation is correct, enter “AT” Command, the screen responds with “OK”. If you ruled out poor quality telephone lines. The site visited by the routing and other external reasons, the situation is still not improved, mostly due to the modem and related software parameters set. “AT, OK” just means that the electrical connection between the modem and the computer is basically correct and information exchange between the modem and the computer is possible. On this basis, a series of parameters should also be set in order to ensure that the system TCP / IP protocol in the implementation of Internet communications correctly in order to achieve a satisfactory Internet access. The Hayes standard AT command set is the industry standard for modem communication interfaces. The AT command set can be used to configure the modem and the calculations it connects to
