Serial-procedure-pc

支持电力规约645，376.1等相关规约的485代码，支持常用电表控制信令代码，(Support the power of the Statute 645,376.1 Statute 485 and other related code, support for common control signaling code meter,)

vc写的基于udp的串口通信简单实例 (Udp serial communication instance, a simple small program)

VC++之MFC串口,包含串口调试助手源程序 及编程详细过程 (MFC serial port)

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

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.)

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.)

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.)

串口测试程序 (Test porgram for serial)

Ymodem传输，基于VC6，可以当串口调试(about Ymodem)

说明：  用数据库实现串口通讯的源代码，功能比较强大，值得一看。(database using serial communication source code, functions more powerful overseas.)
