How to get normal console output?

Question

C++ / C#

cmdProcess = new Process();

var procStartInfo =
  new ProcessStartInfo( "cmd", "/k " );

procStartInfo.RedirectStandardOutput    = true;
procStartInfo.RedirectStandardInput     = true;
procStartInfo.UseShellExecute           = false;
procStartInfo.WindowStyle               = System.Diagnostics.ProcessWindowStyle.Hidden;

procStartInfo.CreateNoWindow = true;

cmdProcess.OutputDataReceived += ( s, e ) => {
  Console.WriteLine( e.Data + "\n" );
};

cmdProcess.StartInfo = procStartInfo;

cmdProcess.Start();
cmdProcess.BeginOutputReadLine();

This code returns output only when the line breaks.
How can I get real-time output, for example from programs like Far Manager?
I most likely need a so-called. screen buffer or something like that
And another question, how can I send CTRL+C to such a console process?
cmdProcess.StandardInput.Write( msg );
Such code will wait for the end of the command output, and I need this to be done asynchronously.
I will be glad to examples, links, manuals.
Thanks in advance!
