多线程，多接收模式串口类 LsComm 之二相关文档 多线程,多接收模式串口类LsComm 作者:Liu_sir 所以参照Delphi中的SpComm设计了一个类CComPort,对CSerialPort进行了2次封装,主要目的是简化串口的使用.使其用简单的代码就可以完成串口通讯的过程.并提供了一个Demo程序演示了CComPort的使用 多线程，多接收模式串口类 LsComm 之二 作者:liu_sir 实现了一个简洁易用的多线程串行通讯接口,可以切换查询和自动接收模式,进行对串口数据收发-Multi-threaded, multi-category serial receive mode LsComm documentation bis multi-threaded, multi-category serial receive mode LsComm Author: Liu_sir Therefore, in light of Delphi SPComm designed a category CComPort, on a 2 times CSerialPort package The main purpose is to simplify the use of serial port. its simple code to complete the process of serial communication. and provided a Demo program CComPort demonstrated the use of multi-threaded, multi-mode receiver serial-type bis LsComm Author: liu_sir implements a simple-to-use multi-threaded serial communication interface, you can switch query and automatically receive mode and proceed to the serial data transceiver
