I have a gnuplot.bat with
    c:\path-to-wgnuplot.exe %*
and I call it with
    gnuplot somescript.plt
where somescript.plt might be something like
    set terminal context
    set output "somefile.tex"
    plot sin(x)
    pause -1
    plot cos(x)
or perhaps
    load "somefile.dem" # any demo file from the distribution

Then a pause windows pops up and wants me to press Enter in order to procee=
d.

I'm still using the "old" windows terminal. Perhaps wxwidgets behave better=
.

I'm not piping (I guess). I'm only calling "gnuplot[.bat]
somescript.plt" from TeX.

Sure, but if I want to test demo scripts out of the box ... I won't
write any pause statements in my scripts (although I still might want
to use the same code for testing the plots where I need pauses and for
producing high quality plots where I would want them to be ignored).

But that can't be used under windows (where I'm experiencing the "problem")=
.
I don't have access to any linux box at the moment, but well ... I can
try what happens there.

GhostScript has -dBATCH -dNOPAUSE switches for the same purpose for example=
.
