The `dumb` terminal driver plots into a text block using ascii characters. It has an optional size specification and a trailing linefeed flag.
Syntax:
set terminal dumb {size <xchars>,<ychars>} {[no]feed}
{[no]enhanced}
where <xchars> and <ychars> set the size of the text block. The default is 79 by 24. The last newline is printed only if `feed` is enabled.
Example:
set term dumb size 60,15
plot [-5:6.5] sin(x) with impulse
