Touching a running programm

Hi

Here is the situation:
I have a running programm, called "circle"
its pid is 9000
I want to give a "message" to it
like -T
how would I do that?
because if I try to run the executable again, it shall open another instance of it
I just would like to give it a command
then my c programm would ready it and make some actions

any help please?

    I would do this by hooking an interupt. I only know how to do it in asm...
