I had the first problem, too, but no real solution. Somehow 'gnuplot' 
disabled echoing of the terminal. You can get it back, if you blindly 
enter ':reload'. Which version of the gnuplot package do you use? Recently 
I have switched to run gnuplot via forkIO. You can download the current 
repository state from:
    darcs get http://code.haskell.org/gnuplot/

However, people have reported that when starting a bunch of gnuplot 
instances, some of them fail to open. :-(
