Chinese RFC documents, without translation, the right to study very helpful!

非常详细的modbus规范介绍，有串口的也有基于tcp的。。。。一书在手，modebus不用愁。。。。MODBUS标准分为三部分。第一部分（“Modbus协议规范”）描述了MODBUS事物处理。第二部分（“MODBUS报文传输在TCP/IP上的实现指南”）提供了一个有助于开发者实现TCP/IP上的MODBUS应用层的参考信息。第三部分（“MODBUS报文传输在串行链路上的实现指南”）提供了一个有助于开发者实现串行链路上的MODBUS应用层的参考信息。-very detailed Modbus standard, a serial port is based on the tcp. . . . A book in hand, do not have to worry about modebus. . . . MODBUS divided into three parts. The first part ( "Modbus protocol specification") describes the MODBUS handle things. The second part ( "MODBUS Packet Transmission in TCP/IP Implementation Guide"), provides a help developers to implement TCP/IP on the application layer MODBUS reference information. The third part ( "MODBUS Packet Transmission in the serial link achieve Guide"), provides a help developers achieve serial MODBUS link on the application layer of reference information.

利用VB写的多线程通讯工具，可以很好的解决串口通讯数据量巨大时阻塞的问题，而且对学习怎样用vb写多线程有很大的帮助-VB write multi-threaded communication tools, can solve serial data communications at a huge obstruction to the problem, but learning how to use Visual Basic to write multithreaded be of great help

带有wsgiref的简单服务器和带有请求的简单客户端。

sim 文件系统In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements. At that former time, people hoped to build a based system, which could access a centralized server network, would always have access to the latest traffic information and could provide web links. What this trend is a momentous request for mobile services based on high-speed packet data transfer. Hence, a new standard, GPRS, came into being in order to fill people’s bill.-sim file system In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements.

移动通讯协议文档，很有参考价值-mobile communication protocol documents, was useful

可以接收GPS GPRMC格式报文的数据，重点是QT做的，对这方便的朋友应该有帮助，这里有串口如何接收的处理，并且集成了串口第三方的类，对于需要QT串口的开发者也是有很大帮助的，串口类已经经过很多的测试了，比较好用。

对原始的 ALOHA 协议的改进是"时隙 ALOHA"，介绍了离散的时隙，并增加最大的吞吐量。一个站可以发送只有初时隙和因而减少碰撞事故。在这种情况下，我们只需要对传输尝试 1 帧时间内不连续 2 帧-次，担心，因为在每个时隙期间只能发生碰撞。
