在dev c++中termios.h头文件无法使用

我在dev c++中编写了一段程序,我想实现“不按回车getchar()”,就用了termios.h这个头文件,但是编译的错误是4 22 C:\Users***\Desktop\未命名1.cpp [Error] termios.h: No such file or directory 。删掉#include <termios.h>之后,一些语句就无法使用,请问怎么解决?或者有没有别的方法能实现“不按回车getchar()”?
代码如下:

#include <iostream>
#include <cstring>
#include <iomanip>
#include <termios.h> 
#include <list>
#include <unistd.h>
#define clear() cout << "\033c" << flush
using namespace std;
