Split into new topic.

You need to read the global sticky topic called Forum Guidelines.

#1 You need at least 3 posts…
#2 Since you're on tekkit I don't think you have the new version ( :P/>) and therefor this should work:

rednet.open(side) --side is a string, for example "left"
rednet.send(id, message) --id a number representing the receiving computer and message must be a string containing your message

...
rednet.close(side) --Only use this when you're done...obviously...

receiving:

rednet.open(side)
id, message, distance = rednet.receive(timeout)
--if timeout is not set it will run until it gets a message.
--id is the id of the computer that has send the message and distance is the dist. between sender and receiver (in blocks)

...
rednet.close(side)

You get the id by simply typing id into the computer's startup screen (the shell)
