[SOLVED] How to stop user input to show on interactive terminal window?

Issue

Here is an example of script:

while true; do 
printf ""
done

Now if I run this script on a interactive terminal it obviously print nothing!

but in same case if I also start typing CHARACTERS and KEYS from my keyboard they will obviously show on terminal window while the script is running interactively.

Example output:

fasd^[[D^[[A^[[Cfsf

I want to temporarily stop user input to show while script is still running.

Thankyou, for any help.

Solution

In my piu-piu project I'm switching user input on and off like this:

...
COF='\e[?25l' #Cursor Off
CON='\e[?25h' #Cursor On

cursor () {
    case $1 in
         on) stty  echo; printf "$CON";;
        off) stty -echo; printf "$COF";;
    esac
}
...

cursor on
cursor off
...
