VB.net的串口通讯支持总是让人觉得有所不足，在使用VB6的MsComm32.ocx时，很多人都会在VB.net的开发中觉得很困扰。这里讲述的VB.net串口通讯类使用native代码，并且它是通API调用实现的，你会发现VB.net的串口通讯就是这么简单。 在说明如何使用这个类前，需要说明的是，本类只是一个VB.net的串口通讯演示，你可能需要根据你的情况修改后使用。-Serial Communication Programs require the support always make people feel inadequate. in the use of VB6 MsComm32.ocx, Many people will Programs require in the development feels very frustrated. Programs require here on the serial communications using native code, and it is the 14th API calls to achieve, and you will find Programs require the serial communication is as simple as that. In explaining how to use this class, there is a need to explain, this is only one type of serial communications Programs require demonstration You may need to change your position after use.
