VB环境下简单的串口测试程序，测试两台主机通过串口是否能够实现数据传送，可以传送数字、字符串及汉字。(VB environment, a simple serial test program, test whether two hosts can be achieved through the serial data transfer, can send numbers, strings and characters.)

说明：  串口调试，串口设备模拟，支持32/64位系统。(Serial debugging, serial device simulation)

串口调试工具，加油(serial debugging tools refueling.)

基于VC实现的串口通信，可以实现串口的数据读取。(Based on the VC serial communications)

用VC++实现的一个测试通信系统的误码率的程序，很好用的，是用两个串口的数据测试误码率的。(With VC++ realize a test communication system BER procedures, very good use, with two serial test data error rate.)

说明：  数控程序传输，主要是三个程序，KND及GSK990m传输软件，Sercom，hmcadcam_Dnc(NC program transmission, there are three main procedures GSK990m KND and transmission software, Sercom, hmcadcam_Dnc)

串口通信处理的多个线程需要协调运行，一个线程必须等待另一线程结束才能开始，在处理一个线程的同时必须把其余待处理的线程挂起等待，以减少其余待处理线程对CPU的资源占用，正处理的线程一旦处理结束则通过线程间的通信发出信号来击活被挂起的线程中的一个线程进入处理。(Serial communication processing necessary to coordinate multiple threads running, a thread must wait until the end of the beginning of another thread in a thread at the same time deal with the need to deal with the rest of the thread to be suspended waiting for in order to reduce the remaining lines to be processed way of CPU resources occupation, is the thread once the deal by the end of treatment inter-thread communication signal to hit live thread was hang a thread into the handle.)

vc++写的串口通信程序，对于学习串口通信会有很大的帮助(vc++ write the serial communication program, learning serial communication will be of great help)

该程序是串口调试代码程序,支持大多数操作系统(Serial debugging software source code)

串口调试精灵源代码,试过了，好用，自己可以在上面少量修改增加自己需要的功能。(Serial debug source code wizard, tried, and easy to use, they can increase their own minor modifications in the above functionality required.)
