Changing terminal for gnuplot

[Alex Roper]

Hi,

How can I control where octave plots things? In particular, I am writing a script and 
don't want it trying to pop up windows all over the place and freaking out when it 
discovers X isn't installed. I used to be able to "set terminal dumb" or something like 
that, but I see this has been removed for matlab compatibility in recent versions.

However, when matlab is run without X, it just works.

Sorry for asking something so simple, but I can't find it anywehre in the docs and google 
is still telling me to "set terminal dumb".
