SerialPort类的源代码已经放在下面，SerialPort类是由Remon Spekreijse提供的免费串口类。 CSerialPort支持线连接的串口编程，而且是基于多线程的，工作流程：
1.设置串口参数。 函数原型：
BOOL CSerialPort::InitPort(CWnd* pPortOwner, // the owner (CWnd) of the port (receives message) UINT portnr, // portnumber (1..4) UINT baud, // baudrate char parity, // parity UINT databits, // databits UINT stopbits, // stopbits DWORD dwCommEvents, // EV_RXCHAR, EV_CTS etc UINT writebuffersize) // size to the writebuffer
2.串口监测线程。
BOOL CSerialPort::StartMonitoring() BOOL CSerialPort::RestartMonitoring() BOOL CSerialPort::StopMonitoring() void CSerialPort::WriteChar(CSerialPort* port) void CSerialPort::ReceiveChar(CSerialPort* port, COMSTAT comstat) void CSerialPort::WriteToPort(char* string) 3.监测线程接收事件信息，再进行消息处理即可。 SerialPort类的应用
基于对话框的串口程序开发：
1.将SerialPort类添加进工程； 2.进行消息的映射；
（注意：在SerialPort类的头文件中的：
#define WM_COMM_RXCHAR WM_USER+7 需要手动进行映射）
