[pstricks] pst-circ, wire without arrow

[Doris Wagner]

hi list,

how can I get rid of the arrow in the following example???

\documentclass{article}
\usepackage{pst-circ}
\begin{pspicture}{4,2}
\pnode(0,0){A}\pnode(0,2){B}
\wire(A)(B)
\end{pspicture}

I tried \psset{intensity=false} and I tried 
\wire[intensity=false](A)(B), but it didn't work...
