The helper process takes input via stdin and prints the result to stdout. Sometimes we find that the from the controlling process into the stdin pipe hangs. Clos...

Pipe in, pipe out.

A customer was having trouble manipulating the stdin stream that was given to a process. How do you simulate sending Ctrl+Z to a hidden console process programmatically? I am using and want to send the console a Ctrl+Z. I've tried sending ASCII code 26, but that doesn't work. supports Ctrl+C and Ctrl+Break but not Ctrl+Z. Here's what I'm ...
