串口开发的另一种方式 最近在整理文件的时候发现了原先写的一个串口程序，为了提高重用性就又重新的写了一下。根据以前的使用过的一系列串口操作软件发现，大多数的串口操作软件不具备自动的记录保存功能，于是我就在这里把它加进去，记录文件是在应用程序目录下以时间命名的文本文件。程序使用了两个可以重用的 C++ 类，串口通讯类文件 superSP.cpp, superSP.h 文件操作类文件 fileCtrl.cpp, fileCtrl.h。 -development in a different way recently in the collation of the documents identified a previously written a serial process, In order to improve reusability also on the re-write a bit. Under the previous use of the series of Serial operating software found, Most of the serial operating software does not have an automatic record-keeping functions, so I was here it added. documented in the application directory time to a text file named. Procedures for the use of the two can reuse the C category, serial communications superSP.cpp document, superSP.h file manipulation fileCtrl.cpp types of documents, fileCtrl.h.

该文件内含两个文件，一个是串口调试助手，另一个是用VC编写串口调试助手的源程序，对串口调试助手及其实现原理感兴趣的，是一个很有用的资料。-The document contains two papers, one is the serial debug assistant, and the other is used to prepare serial debug VC source assistants, assistant to the serial debug and realize the principle of interest is a very useful information.
