 -- This is some simple code i made to get information about a Big Reactor wireless using a Pocket computer.
 -- Place a computer with a wireless modem on the left side and the Computercraft Big Reactor port right behind it.
 -- UPDATE! you need to input the right computer IDs in both programs respectivly
