Wireless pulse send?

Hey guys (pro's)!

Im trying to make a storage facility, and im using computercraft for it. Im making a computer able to give any item the storage facility has to the player.
For example; when you press ''1. Cobblestone (64)'', the computer would send a redstone pulse to a pump on a chest that has cobblestone in it, the cobblestone from there goes to the player.
Though there are many more items in minecraft and I can only set around 5 pulse (left, right, top, bottom and back).
Now my question is, is there a way to send a command to another computer to pulse?

Many thanks!

Just use rednet send a key work for each side you want to pulse.

--Computer 1:
rednet.send(id, "top")

--computer 2:
local id, msg = rednet.receive()
if msg == "top" then
  -- pulse on the top
end
