如何模拟串口进行测试
我需要编写一个设备模拟器用于通过串行端口连接的测试目的。我知道有一些应用程序可以做到这一点，但这并不能真正帮助我的好奇心，哈哈。我想知道如何在 .net 中编写一个嗅探器来监视串行端口上进出的流量。我也对任何人需要什么建议来完成我的测试感兴趣，但我想要 .net 中的东西，而不是第三方下载。
I neeed to write a device emulator for testing purposes that connects through a serial port. I know there are some apps out there to do this, but that doesn't really help my curiousity, lol. I would like to know how in .net I could write a sniffer to watch the traffic in and out on a serial port. I'm also interested in what suggestions anyone has to accomplish my testing, but I want something in .net and not a 3rd party download.

您始终可以在软件中编写虚拟串行端口并将应用程序连接到该端口。有 GPL 驱动程序源代码，应该可以让您开始了解如何执行此操作：

我可能需要补充一点，编写虚拟设备通常涉及编写驱动程序，这显然是在托管语言中无法做到的。
You can always write a virtual serial port in software and connect your application to that port. There is GPL driver source code out there that should give you a head start on how to do it:

I might have to add, writing a virtual device usually involves writing a driver, something you obviously can't do in a managed language.
