When on the receiving end of a pipe less generates output. With less filename you have to play with ^V the space bar and so on. You are in interactive mode.
It's behavior depends on the terminal "type" of stdin. In a script or on the receiving end of a pipe, stdin is not a terminal. less uses termcap based on terminal type to determine base behavior when it is entered on the command line.
I'm guessing this is what you are asking.
