I do remember making 'control panel screens' for our 'Dumb Terminals' using DOS Batch files.
Different departments used different files/software/etc. so I built screens for each that allowed the end-users to 'click' a title on the control panel screen rather than having to use a command line.
I got pretty creative at making imagery out of acsii characters. And when we got color displays it was even more fun.
