Window report sequence
This function enables the dtterm control sequence such as the window status reporting, the window position reporting, the window size(in pixel and character) reporting and the root window size reporting, among the window information reporting features.
If you do not want window information to be sent to remote host by some reason such as security, please disable this setting.
Cursor control sequence
Enables the control sequence for the cursor shape.
This function enables cursor shape change by cursor change sequence of DECSCUSR(cursor shape change), WYSTCURM(Wyse no-blinking cursor), WYULCURM(Wyse underlined cursor) and AT&T 610 blinking cursor.

If a user uses the vim editor, write below entries in the ~/.vimrc to enable this feature.

set t_SI=^[[3\ q
set t_EI=^[[1\ q
NOTE: Input ^[ by using Control-V Control-[.
If the cursor periodically blinks after an application exits, a user should configure as follows.
In the ncurses 5.7 terminfo, the invisible(civis)/normal display(cnorm)/highlighting(cvvis) of the xterm cursor are as follows:
civis=\E[?25l
cnorm=\E[?12l\E[?25h
cvvis=\E[?12;25h
When the upper configuration is enabled, the normal cursor displays with the non-blinking mode and the emphasis cursor displays with the blinking mode. So, the cursor does not blink when the terminfo application displays the own cursor.
If a user want to blink the cursor, turn off the CursorCtrlSequence entry or do in the following commands:
% infocmp xterm > xterm.ti
Open the xterm.ti file, change from a value of cnorm and cvvis to \E?25h.
% tic -o ~/.terminfo xterm.ti
Execute the tic command.
# tic xterm.ti
If the configuration is enabled as whole system, execute the upper command with a root user.
