RS232-ACCESS-DEMO0.0.1

这个程序是利用VC编写的一个从机串口响应modbus查询命令程序，实现RTU方式，3.5和1.5个字符时间检测，CRC和LRC校验。(This program is written using VC as a response from the machine serial modbus query command procedure, to achieve RTU mode, 3.5 and 1.5 characters time detection, CRC and LRC check.)

用vb实现串口间通信,可以用来熟悉串口间传输信息的原理.(with Serial Communication, which can be used with serial transmission of information between the principle.)

简洁的VB串口调试程序。适合初学者学习和参考(Simple VB serial debugger. Learning and reference for beginners)

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!)

C#写的控制串口继电器模块的代码，通过发送指令来控制多路串口继电器的开关。(Serial port control relay module C# to write the code, switch by sending commands to control multiple serial relay.)

串口调试工具，包含自动计算MODBUS crc校验码，是工具非源码(tiaoshi gongju)
