短信控件，无限制版。重要用于串口手机发送短信

Advantech Driver Demo: Software Data Transfer

51单片机的MODBUS的通信协议，学习中。

本文讲述的利用通讯控件发送与接收通讯数据都是基于二进制来实现的，基于文本的情况基本与此类似。要想利用好通讯控件还有其他一些应该注意的地方，比如波特率的设置、接收与发送缓冲区的设置以及通讯过程中的延时问题的处理等等。-This paper describes the use of communications controls send and receive communications are based on the binary data to achieve, based on the basic text of this and similar. To make good use of communication controls should also pay attention to some other place, such as baud rate settings, receiving and sending the buffer settings and communication latency in the process of dealing with such problems.

从串口读取数据，有两种方法，1、每接收一个EV_RXCHAR,就用ReadFile读一次，这样我觉得太恐怖了。2、接收到一个EV_RXCHAR后，等一定数据量的CPU周期(GetTickCount),再一次性读取缓冲区里的数据。这样做，一般情况下不会有问题，但是，如果数据很多，过了“一定数据量的CPU周期”，还没收完数据怎么办？就会少读数据了。 我用三个线程序来完成串口数据的接收，其实就是第一种方法的变种： 一个侦听EV_RXCHAR,一个对EV_RXCHAR进行分析，其实就是超时判断。如果接收到一个消息后，一段时间没收到下一个EV_RXCHAR，就认为是一个数据包的结束。这个线程就会通知数据接收线程，进行数据接收。一般同一包数据，两个字符之间的时间间隔，应该很小了吧，而两个数据包之间的间隔，应该不会太小吧！（这个地方我不清楚，猜的:( :) ）最后一个线程，是接收数据的。-read data from the serial port, there are two methods, one, each receiving a EV_RXCHAR, on the ReadFile read, I think this vote. 2, received a EV_RXCHAR after a certain volume of data, such as CPU cycles (GetTickCount), and the one-time reader, the data buffer. To do so, under normal circumstances there is no problem, but if many of the data, and after a "certain amount of data the CPU cycles," also confiscated End Data how do? Few will read the data. I used three lines to complete serial data reception, the first method is a variant : an interception EV_RXCHAR, one pair of EV_RXCHAR analys

串口通信程序,可以直接执行使用,带有界面容易操作-serial communication procedures, the implementation can be directly used, with the interface is easy to operate

个人写的一个串口通讯程序，希望对大家有帮助。-personal wrote a serial communication program, and I hope to be helpful.

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

传说中很牛的视频压缩处理芯片方案,不过是我的淘汰方案,送给大家供参考-Legend is the video compression chip beef program, but out of my program, send them to Members for information

本软件在C++ Builder 6.0开发环境下编程，实现的功能是：如果将本机的两个串口通讯口COM1和COM2连接起来，可以实现本机内这两个COM口间的数据的传输；若将两台电脑的COM口连接起来，可以实现这两台电脑的串行数据传输。-the software in C Builder 6.0 development environment programming, the functions are : If the machine two serial communication port COM1 and COM2 link up the machine can achieve this within two COM ports of data transmission; if two computers connected to the COM port, This can be achieved two computer serial data transfer.
