This is instead of using good ole Serial Monitor.
Advantage with a terminal program is that when you press a key, it goes to serial then.
Advantage with a terminal program is that the cursor can be moved like on an LCD or TFT.
I started thinking along lines of portable displays, even 4-line LCD's and how I would show lists one item at a time, the same should work if possible on PC terminal but would look very different (and need more code) on Serial Monitor.
But a lot depends on whether or not people are willing to go to the trouble to set up and use a terminal emulator?
My other hope is that some day Arduino might include an ANSI terminal in the IDE, something that can be set for font, columns, lines and baud rate able to show a 132x66 page of greenbar or simulate a 20x2 LCD. Oh yes, I want that!
