I choose what I think are the best Titles based on existing titles/class names and so on. There were also inconsistencies between TX and Transmit and RX and receive. I renamed them to shorter version TX and RX also added it as suffix where possible to make it clearer in what mode you are in. If you have any other title suggestions or changes please use Add comment on Files Changed Screen so I can change it.
