how to make whole terminal readonly ?

[HeiShuXianSheng]

I want to open xterm with two step as blow:
step1: open xterm and print something in screen;
step2: make whole xterm readonly, this way the cursor won't blink and it won't receive input from keyboard keys;

I have finished the first step, but how can i get a readonly xterm?
