DOS下采用中断接收数据的串口通讯的例子,很难找到的好东西!

// ********************* START OF TERMINAL.H *********************
//
// This header file contains the definitions for the base class
// Terminal.  It is a virtual base class, so you can't create an
// instance of it directly; you must derive a class from it and
// implement the pure virtual functions. One example of such a
// class is AnsiTerminal, defined in Chapter 13 of the book.
