I wrote this code to test whether I can print an input from keyboard to the screen.  However, when I run the code, I ended up getting the input printed twice.  Could someone please help me with this?  Thanks

code segment public
     assume  cs: code, ds: code
     org     100h

start:
        mov ah, 1
        int 21h
        cmp al, 36
        jz  done
        push ax
        push dx
        mov dl, al
        mov ah, 2
        int 21h
        pop dx
        pop ax
        jmp start

done:
        int 20h

code ends
     end  start
