Hi,

I have tried your program (I modified "Password:" to "password :"
because of my scp output) and I have also a timeout. May be this is
related that the output of the scp isn't on stdout but somewhere else ?
I tried to redirect to a file without much success.

I have also tried with Err_To_Out set to true without much success.

Maybe somebody else ?
Sorry for being so little helpful.
