很好的串口通信源程序，可以设置端口号，波特率，数据位 停止位校验位(a very complete source serial communications,it is helpful for everybody)

一个功能比较全面的串口调试工具。你值得拥有。(A more comprehensive functional serial debugging tools. You deserve. )

调试使用的串口助手，程序源码，功能齐全，可以调试程序(Serial Port Assistant for Debugging, Program Source Code, Full-featured, Debugging Program)

转载，自己需要一些串口程序与控件的应用知识，希望能够和大家共同学习，共同进步！(reproduce, they need some serial procedures and controls the application of knowledge, and we hope to be able to learn together. common progress!)

本程序调用了微软自带的mscomm控件，实现com口的数据接收，读者可自行添加发送数据功能。内附mscomm.ocx控件及其注册方法，本程序是用的静态链接库，为的是能在没有vc库的机器上也可以运行，所以个头大了点。(Microsoft's own mscomm controls, I realize com data reception, readers can add their own functions to send data. Enclosing mscomm.ocx control and registration method, the procedure is used in the static link library, for the in the absence of vc for the machine can also run, giving the larger point.)

基于VISCA协议开发，用于摄像机串口通信，控制摄像机云台等。例如：向左、向右旋转，变焦等等(Based on VISCA protocol developed for the camera serial communication control camera pan and tilt. For example: to the left, right rotation, zoom, etc.)

COM口设置 串口设定 端口号 波特率 数据位 停止位 校验位 串口数据接收 串口收据发送(COM port settings Serial data receiving Serial receipt)

VC实现和S7-200PLC的串口通信程序,很有价值哦(VC and S7-200PLC Serial Communication Program and of great value oh)

vb 串口上位机 很简单的一个版本，大家自己扩展功能吧 (com executed on pc,it s a simple version ,easy for expansion)
