Description: 这是XMODEM传输协议原代码,测试只能证明错误的存在，而不能表明程序中没有错误。
测试的两个作用是：确定程序中缺陷的存在；有助于判断该程序在实际上是否可用。
软件测试最困难的问题之一是知道何时停止测试(When to stop testing? )
自己测试自己的程序是不可能的。
当一个软件被测出的缺陷数目增加时，更多的未被发现的缺陷存在的概率也随之增加。
-This XMODEM transfer protocol source code, the test can only be proved wrong there and not show anything wrong procedure. The two test role is : procedures for determining the existence of defects; Contribute to the judge whether the procedure can be used in practice. Software testing the most difficult one of the problems is to know when to stop testing (When to stop testing) testing their own procedures is not possible. When a software detected the increase in the number of defects, more undiscovered flaws in the probability has increased.

Description: XMODEM 是一种适合在两个计算机之间进行文件传输的简单协议。嵌入式系统调试环境经常利用此协议或其变体，通过UART 端口进行image 的下载。实践者通过此实验环节可对通信协议的基本要素有较深入的了解，同时对通信协议在实时操作系统环境下的实现方式有初步了解。-XMODEM is a fit between the two computers Simple File Transfer Protocol. Debugging embedded systems often use this protocol environment or its variants, through the UART port for image downloading. Practice through this experiment, could be on the basic elements of communication protocols have a better understanding of communication protocols at the same time in real-time operating system environment to achieve a preliminary understanding of the way.

Description: XMODEM协议是一种串口通信中广泛用到的异步文件传输协议。分为标准Xmodem和1k-Xmodem两种，前者以128字节块的形式传输数据，后者字节块为1k即1024字节，并且每个块都使用一个校验和过程来进行错误检测。在校验过程中如果接收方关于一个块的校验和与它在发送方的校验和相同时，接收方就向发送方发送一个确认字节(ACK)。由于Xmodem需要对每个块都进行认可，这将导致性能有所下降，特别是延时比较长的场合，这种协议显得效率更低。(XMODEM protocol is a widely used serial communication in the asynchronous file transfer protocol. Divided into standard Xmodem and 1k-Xmodem two, the data of 128 byte blocks, the blocks of bytes for 1K is 1024 bytes, and each block with a checksum and the process for error detection in the verification process. If the receiver is about a block and check with it at the sender's check and at the same time, the receiver to the sender sends a confirmation byte (ACK). Because the Xmodem needs are recognized for each block, which will lead to the decline in performance, especially the long delay situations, this agreement is less efficient.
In addition to Xmodem, and Ymodem, Zmodem protocol. Their agreement is similar to Xmodem, the difference is that Ymodem allows batch file transmission, high efficiency; Zmodem is improved by Xmodem, it only needs to damage other block retransmission, the correct block does not need to send a confirmation byte. Reduces the amount of communication.)
