去年我使用Qt编写串口通信程序时，将自己的学习过程写成了教程（Qt编写串口通信程序全程图文讲解），但是由于时间等原因，我只实现了Windows下的串口通信，并没有去做Linux下的。自从教程发布到网上后，就不断有人提出相关的问题，而其中问的最多的就是，怎样在Linux下实现串口通信。因为有计划安排，而且没有开发板，所以一直没能去研究，也就没能给出很好的解决办法。前些天，网友hqwfreefly 用Qt写了一个叫linucom的Linux下串口调试程序，实现了Linux的串口通信。而且，正好现在我有几天假期，所以就和hqwfreefly合作，将linucom更新为Lincom，并且推出了Windows下的Wincom，然后完成了这篇Qt编写串口通信程序的专题教程，也算完成了我的一个心愿。-Last year, I serial communication program written using Qt, it will be written in his learning process tutorial (Qt graphic writing serial communication program to explain the whole), but due to time and other reasons, I just realized serial communication under Windows, and did not go to do under Linux. Since the tutorial posted online, you constantly been raised related issues, which asked the most is how to implement serial communications under Linux. Because of scheduling, and there is no board, so have not been able to study, but also can give no good solution. A few days ago, users hqwfreefly use Qt to write a serial called linucom the debugger under Linux, the Linux implementation of serial communication. And just now I have a few days, so on and hqwfreefly cooperation will linucom update Lincom, and launched under Windows Wincom, then completed the writing of this serial communication program Qt tutorial topics, can be considered completed my a wish.
