Unfortunately, I don't have the source code of the program, so it's no option
to patch it.
I tested mintty: it does not work.
I understand, that there is nothing to do with a pipe to the pty or stdin.
I'm thinking of something like this:
ConsoleKeypressSimulator.exe --delay 10 --key y &
And for proper operation, the DosProgram needs a "y" keypress about 10 seconds
after begin of execution.
So my questions are:
- Is it possible to write such a program: ConsoleKeypressSimulator.exe ?
- If yes, what is the degree of difficulty to write that?
Thanks for your help!
