Hiplot services

To create a permanent record of some of the return maps, subroutines have been added to service a HOUSTON INSTRUMENTS plotter, or any other model which responds to the same commands. There is nothing in the subroutines other than the generation of a stream of ASCII characters directed to a serial output port, but the characters have to be the ones which will activate the plotter.
