Another approach might be in the hardware. Since this board is presently only putting out monochrome, you could replace the RGB resistors with variable trim pots and adjust the colour in hardware.

I agree with you that BOLD, BLINKING , and UNDERLINE may not be possible, but it would be nice to add color selection. The codes that I found are: > > > ESC[3(0-7)m for the color of the character, where the second number can be 0=black,1=red,2=green,3=yellow,4=blue,5=magenta,6=cyan,7=white. For the background the code is ESC[4(0-7)m with the second number having the same color sequence. I was able to check the escape codes on the TeraTerm which is setup for VT100. > > > I do not understand the spin programs so I am not sure how to construct the case situation for the "m" modification of the color.

I downloaded the firmware to run the screen and keyboard as a VT100 terminal. That works pretty well but some of the ESC codes for screen control don't work.
