利用CserialPort串口通讯类进行封装的DLL接口函数库SerialPort

代码说明：

说明：  利用CserialPort串口通讯类进行封装的DLL接口函数库，该函数库使用方便，功能强大，提供打开串口、设置波特率、发送数据、接收数据、关闭串口等功能，支持多线程、多进程使用，在实际应用中经过反复测试，工作稳定。(The DLL interface function library encapsulated by CserialPort serial communication class is convenient to use and powerful. It provides functions such as opening serial port, setting baud rate, sending data, receiving data, closing serial port, etc. It supports multi-thread and multi-process use. After repeated tests in practical applications, the work is stable.)
