What is the dumb terminal ?

gnuplot has a dumb terminal. It is seldom used, but I think it is
funny.

gnuplot> set term dumb
Terminal type set to 'dumb'
Options are 'feed 79 24'
gnuplot> set yrange [0:1.5]
gnuplot> plot [-2:2] exp(-x*x)

In short, plot a graph with letters. When you are working on a TTY terminal,
and you want to see the data trend briefly, this terminal is helpful, sometimes.
Or you can email this graph to your friend.
