Hello,

   I am trying to capture standard output and error from unix shell
running as a child process. I understand that to do so, I need to use
pseudo terminal. But the problem is the slave side combine stdout and
stderr nad print them out together on the terminal. My question is if
there is a way to separate stderr and stdout?

Thanks You,
Peter
