串口的话，vc中有现成的类，好像是CSerial，
我这里有个写好的类
头文件是
// Serial.h
#ifndef __SERIAL_H__
#define __SERIAL_H__
#define FC_DTRDSR 0x01
#define FC_RTSCTS 0x02
#define FC_XONXOFF 0x04
#define ASCII_BEL 0x07
#define ASCII_BS 0x08
#define ASCII_LF 0x0A
#define ASCII_CR 0x0D
#define ASCII_XON 0x11
#define ASCII_XOFF 0x13
class CSerial
{
public:
CSerial();
~CSerial();
BOOL Open( int nPort = 2, int nBaud = 9600 );
BOOL Close( void );
int ReadData( void *, int );
int SendData( const char *, int );
int ReadDataWaiting( void );
BOOL IsOpened( void ){ return( m_bOpened ); }
protected:
BOOL WriteCommByte( unsigned char );
HANDLE m_hIDComDev;
OVERLAPPED m_OverlappedRead, m_OverlappedWrite;
BOOL m_bOpened;
};
#endif
