仅作自己学习使用

1 准备部份

串口通讯需要两个调试软件commix和Virtual Serial Port Driver，分别用于监视串口和创造虚拟串口。网口通讯需要一个网口调试助手，网络上有很多资源，我在这里采用的是微软商店中的TCP/UDP网络调试助手，其中也有和commix一样功能的串口调试模块。

第一个软件是这样的：
commix 1.4
资源在这里：免费下载：Commix
也可以前往官网下载：Bwsensing— Attitude is everything
在这里插入图片描述
点击Download即可

第二个软件是这样的：
Virtual Serial Port Driver Pro
官方下载链接：Virtual Serial Port Driver

第三个软件是这样的：
TCP UDP网络调试工具
可以看到其实这个软件也有串口通讯调试的功能。

2 串口通讯

2.1 Xaml代码

界面做得很丑，能用就行，关键是原理：
