使用Kermit协议传输文件的程序-Using kermit protocol to transfer file

进程通信管道模拟，上课时的作业留下的程序，经过老师修改课执行-process communication channel simulation class left the operating procedures are followed, the implementation of the teachers change classes

此程序根据不同的场景采用对应的方法预测无线通信中的链路信噪比，根据预测信噪比选择合适的编码效率和调制阶数进行链路自适应，以此应对过时信噪比对系统性能带来的恶劣影响。

PC机与智能仪表通过串口进行通讯的示例,供初学这使用

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.
