Serial port terminal software to view send/receive data communications.

应用背景主要是应用在电子射频、通讯等行业，例如采样中的数字本振信号、接收机的发射信号等等，还可以用做测试中做一个幅值可调的信号发生器，频率源等，为测试和设计带来很大的帮助关键技术数字信号发生器   DDS  频率可调 。运用MATLAB生成相关 的原 始数据，根据按键改 变频率 控制字，不断地累加，就可以实现频率可调。将生成的二进制代码发送给对应的DAc芯片的数据接口，通过给后端的模拟信号进行简单的硬件上的滤波，即可解决信号的高次谐波。

对于做串口程序的人来说，简直就是雪中送炭-Serial port to do the procedure for anyone who is simply a temporary relief

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.
