以编程方式更改COM端口号 [英] Programmatically changing a COM port number

问题描述

大家好，

我有一个USB到RS-232设备，可用于与各种设备进行通信.但是，每当我将其插入USB端口时，COM端口号就会从上次插入时改变，例如，昨天它注册为COM1，今天是COM8.
现在，我知道我可以进入设备管理器并手动进行更改了，但这很痛苦.我想编写一个可以运行的脚本，它将查找我的设备，获取为其分配的com端口号，并将其更改为所需的数字(例如，我一直希望它为COM1).
我之所以需要它，是因为我正在使用一个商业应用程序，该应用程序设置为仅使用该特定的COM端口.
那么，我从哪里开始呢?

谢谢，

Sean

Hello All,

I have a USB to RS-232 device which I use to communicate with various equipment. However, whenever I plug it into a USB port then COM port number changes from the last time I plugged it in, for example, yesterday it registered as COM1 and today it is COM8.
Now, I know I can go into the device manager and change it manually, but that is a pain. I would like to write a script that I can run and it will look for my device, get its assigned com port number and change it to the number I want (for example, I always want it to be COM1).
The reason I need this is because I am using a commercial application that is set to use only that particular com port.
So, where do I start?

Thanks,

Sean

好吧，第一条也是最好的建议是将您的商业应用程序"丢进去，并将开发此产品的公司列入黑名单:).好吧，除了笑话...

如果您负担不起这一步，则有一类名为"COM Port Redirector"的实用程序.它会成功的.参见:

Well, first and best advice would be to trash your "commercial application" and blacklist the company which develop this stuff :). Well, beyond the jokes...

If you cannot afford that step, there is a class of utilities called "COM Port Redirector"; it will do the trick. See:
