摘　　要：首先论述了自动检测PC机上所存在的串行通信端口(COM)及其设备名的方法;接着介绍了一种自动检测各通信端口上所连接的工业测控仪器的手段;随后提出了应用软件对工业测控设备所连接的COM端口在发生不可预先确定的变化时的自适应编程方法;最后用一个典型的例子验证了所提出的方法和措施的有效性。A method for detecting the serial communication ports（COM） existed on a PC and their device names is discussed firstly.Then the ways to detect and recognize measurement instruments or devices and their connected COMs are analyzed.Later,a programming technique is introduced for application software to communicate with its scheduled instruments without needing to know which COM port a given instrument is connected to.At the end,an example is given to verify all the proposed methods.
