51单片机的MODBUS的通信协议，学习中。

Evc 4.0写的，关于wince 串口通讯程序，通讯规约遵循dl/t645-err

一个串口通信的例子，简单的。。可以先学习。-Example of a serial communication, simple. . Can learn.

串口通信该有的都有了,而且样子也不错.大家看后多给意见咯,对了如果有更好的创已请于我联系-the serial communication have some, but looks good. We see multiple views to argue for the better if the founding has been requested to contact me

260 ad采样-260 sampling ad

这是一个对modem编程的一个小程序, 对串口操作并发AT指令集.-this is a modem programming of a small program on serial operation with AT command set.

金卡（gold card),俗称84卡，即采用pic16c84芯片的智能卡，读写编程程序。用vb4写的。-gold card (gold card), commonly known as 84 cards, the chips used pic16c84 smart card reader programming procedures. With vb4 writes.

一个模拟主站的CDT调试工具。可以根据需要来设置同步字，控制字，信息字的颜色。挺好用的。-A simulated Master Station CDT debug tools. May be needed to set the synchronization word, control word, the color information word. Very good use.

此串口调试程序加入了三菱PLC通讯调试，有源码及运行程序

VC串口编程实例，调试过。使用时，最简单就是将计算机串行发送（TXD）与接收（RXD）短接。-VC serial programming examples tuned. When used, the simplest is to send computer serial (stage) and receiving (RXD) Short.

把DS18B20获取来的4字节数据每隔一段时间发送到PC,在串口调试助手上可以看到温度数据.-The DS18B20 the past four bytes of data to obtain from time to time sent to the PC, the serial port debugging aids can see the temperature data.
