串口通信控制XX变频器,VB下编的界面，已调试通过，可以运行，...

本软件在C++ Builder 6.0开发环境下编程，实现的功能是：如果将本机的两个串口通讯口COM1和COM2连接起来，可以实现本机内这两个COM口间的数据的传输；若将两台电脑的COM口连接起来，可以实现这两台电脑的串行数据传输。-the software in C Builder 6.0 development environment programming, the functions are : If the machine two serial communication port COM1 and COM2 link up the machine can achieve this within two COM ports of data transmission; if two computers connected to the COM port, This can be achieved two computer serial data transfer.

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.
