在Windows环境下实现串行口的实时检测

Implement the Real-time Detection of Serial Ports in Windows Environment

从实际需要出发，讨论了在Ｗｉｎｄｏｗｓ环境下如何实现对串行口的实时检测．实现了 Ｗｉｎｄｏｗｓ下数据库与外部设备通过串行口进行数据传递．实际应用证明，该系统效率高，精 度高，达到了预期的效果．

To meet practical need, it is discussed for the way to implement the real time detection of serial ports. And the data transfer is accomplished through the serial ports between database and peripherals, in Windows enviroment. Paractical application show that this system is of high efficiency, high precision, and works well as we expected.
