这是一个西门子 ModBus 协议的通讯调试软件。（原码）

我个人收集的C++builder 多线程串口通信方面的-my personal collection of multi-threaded C builder of serial communication Wanton

楼宇自控系统 顾名思意。 （注意：需要专用硬件支持。）-Building Automation System Advisory Board were thinking Italy. (Note : the need for dedicated hardware support.)

《VC++ 和VB串并口开发技术工程应用实例导航》一书的配套源代码，第1章 串口编程调试精灵，第2章 云台镜头控制系统，第3章 电话自动应答系统，第4章 短信实现远程监测系统，第5章 步进电机控制，第6章 来电显示客户管理系统

众志-863系统芯片 USBDC（univer serial bus devce control通用串行总线设备控制芯片，以下简称USBDC）是和带有USB主机控制器的设备进行通信的支持部件，实现和带有USB主机控制器的设备进行数据交换。 USBDC和APB连接进行寄存器的初始化配置，和DMAC连接进行大量的数据交换。-USBDC system-on-chip (Univer serial bus control devce Universal Serial Bus device control chips, hereinafter referred USBDC) and USB host controller with the communications equipment of support components, to achieve and with a USB host controller equipment for data exchange. USBDC and APB connection configuration register initialization, and DMAC link for the exchange of large amounts of data.

本源码主要是通过API函数实现串口打开，读写串口和关闭串口。-the source mainly through API functions Serial opened, read and write serial and serial closed.

实现数据链路层 串口间的通讯，可以调试网络间的简单连接-Data link layer communication between serial port, you can debug a simple connection between networks

DOS下，异步串口通信C代码，根据具体需要可裁减-DOS, asynchronous serial communication C code, according to the specific needs can be trimmed

向串口发送数据，在从串口接数据，需要注意的是把2、3脚短路。-to send data from the serial data access, it needs attention is 2,3 feet short.

serial.h serial.cpp 共两个文件，VC串口封装API类-serial.h serial.cpp a total of two documents, VC serial API Class Packaging

此程序利用串口读取民航AFTN电报网中的AFTN信息，然后进行电报解读，并将解读出来的信息存储到数据库中。是民航常用的电报数据读取端口-use of this procedure to read CAD AFTN serial cable network AFTN the information and then proceed telegram read, and read out the stored information to the database. CAD is used to read the data cable port
