上传个考勤系统,希望别人也能用.该代码只能算初级的东东,软件代码复用性不高,重复代码比较多.唯一感觉有点取鉴的可能就是端口和dll的连接,还有线程的使用,本想改一改,但是手头没有考勤机了,对应考勤机是890C的.-From a performance appraisal system, I hope others can use. The code can only count the primary Dongdong, software, code reusability is not high, repeat the code more. The only feeling a little check Kam is probably dll ports and connections, There are threads to use, simply wanted to, but do not have attendance machine, and the corresponding attendance machine is the 890C.

用TC的API函数写的串口通讯程序。 对串口的访问 。-the API function to write the serial communication program. Right Serial visit.

获取当前机器的COM口的数量，包括usb转换的串口-access to the current machinery of the number of COM ports, including USB Serial Conversion

这个是串口的基于停止等待协议原理编程，这个是接收程序，很好用哦-this is the agreement on principle to stop waiting for the program, this is the receiving process, oh well spent
