Serial Communication Inverse mode

[titanvision]

INVERSE means ? A. write the text backwards, B.send data inverted as opposed to true? , C.make the text appear as white blocks with text inside them? D. Other ?
Please help us help you.

First I would like to thank you, but I do not know how to answer you, since your kindness i would like to share opinions that maybe others can benefit from this topic.

API used for the get correct ATR answers from Smart Cards (ISO 7816 standard)

So I Need to build Application That I can Analyze Communication Protocols between Host and Card.

Okay So I attached partial Code that it may help you to understand what I am doing
Thanks Again.
