    When I run the following command from a terminal, I see the output.
    I wanted to put it in a proc. But the script gets no data.

    It may just be a Windows thing but if it is not, how do I make this work?

    % set f [open "|C:/Windows/System32/cmd.exe /Q /C ipconfig" r]
    % fconfigure $f -blocking 0 -buffering full

    Thank you. I think I am doing all of the steps there. I did not
    include it before but I also setup a readable handler right after.

    I gave it a try, and I noticed that after the open, a black window
    appears and immediately disappears... I'm pretty sure that this
    is the window of cmd.exe appearing and immediately taking ipconfig's
    output with it to the digital nirvana/afterlife.
    cmd.exe itself doesn't produce output, so that's why you don't get
    to see any input from the pipe.

    Try this instead:

    % set f [open "|ipconfig" r]

    or, if you don't want to rely on search path, then this one:

    % set f [open "|C:/Windows/System32/ipconfig.exe" r]

    This seems to do just what you seem to have expected.

    Thanks. Yes, I was doing some searching and this is the answer. It turns
    out that cmd itself generates no output. FYI, the /Q and /C were to
    turn off the windowing/interactive mode so it doesn't need user input
    and stay around afterwards. Your suggestions work fine.
