vb演示Mscomm各种通信功能-vb demonstration of various communications functions Mscomm

C语言通讯程序库DOS版,支持10个115200波特率的通讯口-C language library DOS version of the communication process to support 115200 baud rate of 10 communications port

常见的串口通信程序，用过使用C#语言，利用控件实现串口的实时通信-common serial communication program, used to use C# language, the use of controls to achieve the real-time serial communications

一个包含了几乎所有串口操作的源码群，可以根据自己需要改写-1 contains almost all serial-source operating groups, according to their own needs rewriting

eVC下操作串口提取GPS有效数据2，把文件名的后缀.rar去掉即可，不要解压缩。-operate under effective Serial GPS data from two, the file name suffix. Rar be removed, not decompress.

串口通讯经典使用程序5,以前收集整理的东东,希望对大家有用!-Serial Communication Classic to use the program 5, previously collected Dongdong finishing the hope for all of us!

基于vb的西门子plc和上位机通信的实现方法 拷贝就行-vb-based Siemens plc and the personal computer communications method copy OK

rs485通信协议的规定，定义了串行通信协议中传输的信息内容及使用格式，可以参考-rs485 communication protocol requirements, defines the serial communication protocol to transmit the information content and the use of format

QSS设备读取的后台服务程序，有多线程设置读取QSS，数据存储-Os equipment to read the background of service procedures, how to read threads set Os, data storage

自己使用VB编写的串口通信程序，1号和2号。将两个COM口用串口线连接，就可以运行这两个程序了。实现的功能：1号程序随机发送两个数字，2号程序接收并进行计算，然后发回1号机，1号机接收并显示出来。-its own use VB prepared by the serial communication program, 1 and 2. The two COM ports with serial line connectivity, it can run on the two proceedings. The functions : 1 random procedure to send two figures, the No. 2 receiver and procedures for calculating and then sent back No. 1, No. 1 receiver and displayed.
