如何以编程方式（在 C/C++ 中）模拟 DOS 中的击键？
首先，我谈论的是 DOS，而不是 Windows 的命令行应用程序。
我希望编写一个程序，将击键发送到当前正在运行的进程。 我的目标是在 ISR（中断处理程序）中使用此过程。
换句话说，这就是我想要发生的事情：
- DOS 启动。
- 我运行一个 TSR，它将我的程序注册为某个中断的 ISR（不是键盘中断，但现在我们假设它是）。
- 我运行另一个程序，该程序成为当前正在运行的进程。
- 发生上述中断。
- 我的程序跳入并模拟击键，事实上，这从未真正发生过。
- 当前运行的进程接收此击键，就像实际按下了模拟键一样。
我找到了几个具有不同示例的来源，但我无法真正找到任何适合我的东西。
我不知道它是否有任何相关性，但我现在用来测试所有这些的包括在 VirtualBox 机器上运行的 FreeDOS，以及用于编译和运行代码的 DJGPP（我相信它使用 GNU 编译器） 。
任何和所有的帮助将非常感激。
First off, I'm talking about DOS, and not Windows's command-line application.
I wish to write a procedure that would send a keystroke to the currently running process.
My goal is to use this procedure in an ISR (interrupt handler).
In other words, this is what I want to happen:
- DOS boots up.
- I run a TSR which registers my procedure as an ISR for some interrupt (not the keyboard interrupt, but for now let's assume that it is).
- I run another program, which becomes the currently running process.
- The aforementioned interrupt occurs.
- My procedure jumps in and emulates a keystroke, which, in fact, never really happened.
- The currently running process receives this keystroke as though the emulated key was actually pressed.
I found several sources with different examples, but I couldn't really get anything to work for me.
I don't know if it's of any relevance, but what I'm using at the moment to test all this includes FreeDOS running on a VirtualBox machine, and DJGPP for compiling and running the code (it uses the GNU compiler, I believe).
Any and all assistance would be very much appreciated.

IIRC 你必须使用 BIOS 调用 INT 16h, FUNC 05H ...？或者直接写到 0040:001E（或者是 001C）...谷歌搜索会出现一些关于该主题的线程...
