gnuplot turns off terminal echoing in GHCi

[Lemming]

In some configurations, if you call 'plotFunc' from ghci then you can no longer see what you type in ghci. It seems that 'gnuplot' turns off Echo mode. I do not know why this happens and what I can do against it. Calling ':! reset' does not help. But ':reload' helps. These commands have to be typed in blindly, of course. However, after reload in GHCi all local bindings are gone.
