in reply to send ctrl+c to open3?

Let me se if I understand correclty:

You are running PERL scripts on Windows, through some client that connects you to Linux. And now you want to use a CTRL+C command in WINDOWS to terminate the current ran PERL script. Yet CTR+C is also a command that terminates anything in Command Prompts / lines and it terminates your Windows Command , but does not terminate the PERL's script. Correct?
