realized Modbus RTU communication protocol COM

我用vb编写modbus协议,拿出来与大家分享一下，厚厚，希望得到大家的指教-Modbus protocol prepared hard to share with you some thick hope to enlighten all

vc实现的一个串口通讯例子-vc achieve an example of serial communications

串品通讯 内置MODBUS协议与GSDCS协议 -uartport include modbus and gsdcs

要完成串口通信, 在32位模式下, 一般说来有以下四种方法-to complete the serial communications, in 32-bit mode, in general the following four methods :

是关于山特电源通信规约的串口通信程序，功能是把电源监控器的采集数据上送到规约前置机中。-GOLD comunication rule

计算机中传输数据的方式有两种：并行方式和串行方式。在IBM PC机的汇编语言中，对串口的编程方式有DOS和BIOS 系统功能中断调用。本次实验设计采用BIOS系统功能中断调用，即通过INT 14H，调用ROM BIOS串口通信例行程序。-computer transmission of data in two different ways : parallel and serial mode approach. IBM PC assembly language, the serial programming method DOS and BIOS interrupt function call. The experimental design using BIOS interrupt function call, through INT 14H, called ROM BIOS serial communication is a routine procedure.

这个是用串口下载文件到交界处单片机的代码，而且可以用单片机接收数据用于显示，我们自己使用的工具的-serial download files to the junction of microcontroller code, and SCM can be used for receiving data, we use the tools

很多串口调试助手中串口流控的设置都不起作用，该文章讲述了流控的具体设置方法-Assistant in a lot of serial debugging serial flow control settings are not working, the article describes a specific set of flow control methods
