UDP

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.)

说明：  我所见过用VC写的最好的串口类，具有模拟单片机中断传输的方式，避免了查询传输CPU损耗和接收超时(I have ever seen VC was the best serial category, with simulation SCM interruption of transmission, so that the CPU for transmission and reception of overtime loss)

带ID的lpc2368 CAN通信，包括初始化、中端、CAN通信和串口通信(With the ID lpc2368 CAN communications, including initialization, in the end, CAN communications and serial communication)

485多机通讯的连接方式，主要有总线方式、星形方式等(connection of multi pc communication with 485)

说明：  串口通信高级编程提供了一个能够进行串口通信的类，能够方便地进行各种数据通信。 由于本程序设计到硬件编程，因此，如果读者的串口通信设备 没有连接好，可能会有问题 (Serial communication provides a high-level programming to carry out the type of serial communication, the ability to easily carry out a variety of data communications. Since the hardware design to programming, so if the reader' s serial communications equipment is not connected well, there may be some problems)

说明：  串口编程调试精灵是一种串口编程的调试精灵(Wizard is a serial programming and debugging, the debug serial port programming wizard)
