VC++串口通信设。本书详细说明讲解了在VC++环境下编写串口通信得过程。值得一看

#ifndef FACTORY2_H
#define FACTORY2_H

// Get needed include files
#include "IFortune.h"

// New class declaration
class ComFortuneTellerFactory : public IClassFactory

   STDMETHODIMP         QueryInterface(REFIID, PPVOID);
   STDMETHODIMP_(ULONG) AddRef();

   //IClassFactory members
   STDMETHODIMP         CreateInstance(LPUNKNOWN, REFIID, PPVOID);
   STDMETHODIMP         LockServer(BOOL);
