串口助手 12m波特率

串口助手是一款用于串口通信的软件工具，可以通过串口与其他设备进行数据通信。12m波特率表示每秒钟传输的数据位数为12兆比特。串口助手可以帮助用户通过串口与支持12m波特率的设备进行数据交互。

使用串口助手进行串口通信需要首先连接串口设备和计算机，并确保串口助手已正确安装。打开串口助手后，可以选择相应的串口号和波特率，其中波特率设置为12m。

一旦串口助手与目标设备建立了合适的通信链接，用户可以在串口助手中进行数据的发送和接收操作。通过串口助手，用户可以发送命令、控制指令、数据等信息到目标设备，同时也可以接收目标设备传回的数据。这样，用户可以与目标设备进行双向通信和数据交互。

在串口助手中，用户可以设置不同的数据格式和显示方式，例如，ASCII、Hex等。这样，用户可以根据需要来解析和显示接收到的数据，方便进行数据分析和处理。

总之，串口助手配合12m波特率可以实现串口设备与计算机之间的高速数据传输和通信。它为用户提供了一个方便和易用的界面，使得串口通信更加简单和高效。

需要注意的是，本程序使用了一个名为“CSerialPort”的类来实现串口的打开、关闭、发送和接收数据的功能。该类的实现代码如下：

class CSerialPort
{
public:
    CSerialPort() {
        m_hComm = NULL;
        m_hWnd = NULL;
        m_nComPort = 1;
        m_nBaud = 9600;
        m_nDataBits = 8;
        m_nStopBits = ONESTOPBIT;
        m_nParity = NOPARITY;
    }

    ~CSerialPort() {
        Close();
    }

    BOOL Open() {
        Close();

        CString strCom;
        strCom.Format(_T("\\\\.\\COM%d"), m_nComPort);
        m_hComm = CreateFile(strCom, GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);
        if (m_hComm == INVALID_HANDLE_VALUE) {
            return FALSE;
        }

        DCB dcb;
        GetCommState(m_hComm, &dcb);
        dcb.BaudRate = m_nBaud;
        dcb.ByteSize = m_nDataBits;
        dcb.StopBits = m_nStopBits;
        dcb.Parity = m_nParity;
        SetCommState(m_hComm, &dcb);

        COMMTIMEOUTS timeouts;
        timeouts.ReadIntervalTimeout = MAXDWORD;
        timeouts.ReadTotalTimeoutMultiplier = 0;
        timeouts.ReadTotalTimeoutConstant = 0;
        timeouts.WriteTotalTimeoutMultiplier = 0;
        timeouts.WriteTotalTimeoutConstant = 0;
        SetCommTimeouts(m_hComm, &timeouts);

        SetCommMask(m_hComm, EV_RXCHAR);

        return TRUE;
    }

    void Close() {
        if (m_hComm) {
            CloseHandle(m_hComm);
            m_hComm = NULL;
        }
    }

    int Read(LPBYTE lpBuf, int nCount) {
        DWORD dwRead = 0;
        if (m_hComm && ReadFile(m_hComm, lpBuf, nCount, &dwRead, NULL)) {
            return (int)dwRead;
        }
        return 0;
    }

    BOOL Write(LPCTSTR lpBuf, int nCount) {
        DWORD dwWritten = 0;
        if (m_hComm && WriteFile(m_hComm, lpBuf, nCount, &dwWritten, NULL)) {
            return TRUE;
        }
        return FALSE;
    }

    HWND m_hWnd;
    int m_nComPort;
    int m_nBaud;
    int m_nDataBits;
    int m_nStopBits;
    int m_nParity;

protected:
    HANDLE m_hComm;
};

该类的实现使用了Win32 API中的串口相关函数，可以通过修改该类的实现来适应不同的需求。
