这是一个串口通信的完整源代码，能够设置波特率和选择串行口，可以对程序进行修改以便各取所需。-This is a complete serial communication source code, be able to set the baud rate and select the serial port, you can modify the program in order to take what we need.

这是一个封装得比较完整的串口类，支持同步、异步操作，使用简单高效，具有工业强度，我在BC, BCB, VC, BCBX, GCC下编译通过-This is a relatively complete package-type serial port to support synchronous, asynchronous operation, using a simple high-performance, industrial strength, in my BC, BCB, VC, BCBX
