Hi Barry, have you got any pointers to documentation or reverse engineering attempts for that console protocol? 2009/4/21 Christopher Faylor: > It can be done using the same technique as Console2: > > http://console.sourceforge.net I don't understand how. ReadConsoleOutput() on the hidden console only gives you the cooked output in terms of character cell contents and attributes, whereas the raw output as it came from the console app would need to be sent to the pty to be displayed by the likes of screen. As far as I can see, recreating the raw output from the cooked one isn't possible in general.
