To run MGED on the tek4014 class of terminals one needs to have TWO terminals - the graphics terminal (4014 or one which emulates a 4014) and another terminal to enter commands on.
The procedure is as follows:
ill put up a desired path center slew the display size zoom the display sed solid edit immediately
The main force behind the writing of a driver for the tek4014 terminals was to allow the use of the Teletype 5620 terminals. These graphic terminals have an internal processor and different windows can be set up which represent different terminals. Hence two terminals are NOT necessary. The use of the Teletype 5620 terminals is then the same as the procedure outlined above, except each window represents a terminal.
