I don't know if this is relevant to this discussion, but when I
designed the original UMENU () in 1999, my screen clear was 25
newlines. I did this to work on absolutely any terminal, including a
teletype.

Here's an example:

#include <stdio.h>
int main(int argc, char * argv[]){
        int i;
        for(i=0; i < 25; i++){
                putchar('\n');
        }
        return 0;
}

For small size and fast loading, compile as follows:

gcc -Wall -s -Os -o nl25  nl25.c

Now, in your window manager, if you set a hotkey to run nl25, 25
newlines appear to clear the screen. I can't imagine a terminal it
wouldn't work on, including a teletype terminal.

As I mentioned, I have no idea if this is acceptable under your
scenario.
