本文介绍了一种在Symbian OS v9平台上手动创建GPRS互联网接入点(IAP)的方法，包括生成所需的表格条目来配置模拟器的WAP IAP初始化选项。详细展示了创建IAP所需的各种组件如Bearer、Network、Service等的代码实现。

生成GPRS互联网接入点（IAP）

为了生成 Point">IAP，我们需要使用CCommsDatabase下列代码手动生成了所有所需的table entry，它实际上复制了模拟器的"Winsock" IAP初始化选项。 CreateNewIAP()为主要生成函数.

需要在mmp文件中添加commdb.lib链接库
LIBRARY commdb.lib

代码需要WriteDeviceData能力，在基于Symbian OS v9的手机上运行，所以要在mmp文件中增加

Capability  WriteDeviceData
