2.2.5 向串口写入数据函数 writeData 用于向串口写入数据。成功时返回写入字节数，失败时返回-1。失败时可调用itas109::CSerialPort::getLastError()获取错误码。2.2.6 从串口读取指定长度数据函数 readData 用于从串口读取指定长度的数据。正常时返回读取字节数，失败时返回-1。失败时可调用itas109::...

除了利用Read()方法来读数据,还可以使用ReadExisting()方法来读取数据。该方法读取当前所能读到的数据,以字符串的形式返回。 7 事件 SerialPort 提供了DataReceived事件。当有数据进入时,该事件被触发。该事件的触发由操作系统决定,当有数据到达时,该事件在辅助线程中被触发。辅助线程的优先级比较低,因此并不能确保...

Removed the CSerialPort::DataWaiting method as it depends on the port being open in overlapped mode. Instead client code can simply call CSerialPort::WaitEvent directly themselves. Removing this method also means that the CSerialPort::m_hEvent handle has not also been removed. The CSerialPort::...
