用VC^＋＋实现多线程方式下的串行通信

摘要：结合实际工程，在VC 环境下通过采用创建事件对象来保持线程同步、利用两个监听函

数提高数据接收效率和可靠性等措施实现了多线程串行通信，完成了工程前端数据采集器与后台

计算机之间的数据传输。

Abstract：Combined with an actual project，the data transference between a data collector and a

computer was realized by means of multiple threads serial communication under the VC

environment by adopting measures of creating event object to keep synchronous among threads

and making use of two monitor functions to increase data receiving efficiency．
