正确连接微机、MODEM和电话线后,进行拨号上网操作时,如果MODEM没有拨号音,始终没连接上或指示灯没闪烁,表明MODEM没有执行拨号操作,造成该种故障的原因很多,现分析如下: 1.上一次使用时能否正确执行拨号操作,若上次使用时能拨号而现在不能拨号,请参见第2步,否则转到第5步。 2.最近是否修改过有关MODEM、串行端口的设置,若修改过,请将相关参数恢复成修改前的设置再试。如果问题解
The correct connection of the computer, MODEM and telephone line, dial-up operation, if there is no dial tone MODEM, the connection is always not or flashing lights that MODEM did not perform dial-up operation, causing such a failure for many reasons, are analyzed as follows : 1. The last dial-up operation can be performed at the last time. If you can dial when using last time, you can not dial now. See step 2, otherwise, go to step 5. 2. Whether the MODEM, serial port settings have been modified recently, if the changes have been made, please revert to the parameters before revising the settings and try again. If the problem solution
