Where ICT has RTT send and receive capabilities, displayed sent text shall be visually differentiated from, and separated from, received text.
NOTE: The ability of the user to choose between having the send and receive text be displayed in-line or separately, and with options to select, allows users to display RTT in a form that works best for them. This would allow Braille users to use a single field and take turns and have text appear in the sequential way that they may need or prefer.
