CharFilter_Class实例是对CharFilter实例的完善。在CharFilter实例中，我们定义了四个全局变量，这不符合WDM驱动程序的要求，它限制了IRP的可重入性，我们应该使用局部变量。 该实例定义了一个READ_COMPLETION_INFO结构，当有DeviceControl 调用时，就分配一个结构对象，参数设置完后，就将该结构对象地址指针放在I.FileObject()->FsContext中。 -CharFilter_Class CharFilter example of the perfect examples. In CharFilter example, we define four global variables, which does not conform to the WDM driver, which limits the IRP, can be used, we should use local variables. The examples READ_COMPLETION_INFO definition of a structure, when DeviceControl call, on the allocation of a target structure, parameter setting after the end of this structure on the address pointer on the object I.

　调制解调器是一种使计算机通过电话线路通信的设备。使用调制解调器，您可以向另一台配有调制解调器的计算机发送数据。这使您可以从全球网 (World Wide Web) (正如您现在所做的一样) 中下载信息、发送和接收电子邮件 (e-mail) 及与远程对手玩计算机游戏。一些调制解调器还能发送和接收传真及语音电话呼叫。 　　不同的调制解调器通信速率也不相同。许多新型的调制解调器能以 33.6 kbps 的速率发送和接收数据；以 14.4 kbps 的速率发送和接收传真。一些调制解调器能以高达 56 kbps 的速率从 Internet 服务供应商处 (ISP) 下载信息。 -modem is a type of computer through the phone line communication equipment. Use a modem, you can to another modem equipped with a computer sent the data. This allows you to a global network (World Wide Web) (as you are doing the same), download information , sending and receiving electronic mail (e-mail), and long-distance rivals playing computer games.
