利用短信远程关闭计算机
请问:
GMS.GSMModemGetDevice();的命名空间是什么?
如何实现用短信远程关闭计算机?

[解决办法]
（2）GSMModemGetDevice函数

该函数获取当前的通讯端口，代码如下：

[DllImport("dllforvc.dll",

EntryPoint = "GSMModemGetDevice",

CharSet = CharSet.Ansi,

CallingConvention = CallingConvention.StdCall)]

public static extern string GSMModemGetDevice();
