Carriage Return (CR)

This sequence always unsets the pending wrap state.

If origin mode (mode 6) is enabled, the cursor is set to the left margin of the scroll region and the operation is complete.

If origin mode is not set and the cursor is on or to the right of the left margin, the cursor is set to the left margin. If the cursor is to the left of the left margin, the cursor is moved to the leftmost column in the terminal.

CR V-1: Pending Wrap is Unset

cols=$(tput cols)
printf "\033[${cols}G" # move to last column
printf "A" # set pending wrap state
printf "\r"
printf "X"
echo

|X________A|

CR V-2: Left Margin

cols=$(tput cols)
printf "\033[1;1H" # move to top-left
printf "\033[0J" # clear screen
printf "\033[?69h" # enable left/right margin mode
printf "\033[2;5s" # set left/right margin
printf "\033[4G"
printf "A"
printf "\r"
printf "X"
