It goes in the packet structure rednet uses, under the key "sProtocol". Take a look through the rednet API code and you should see how it's used.

As a basic outline, rednet.send takes your message, the protocol, and one or two other bits of info, and bungs them in a table. That table then gets sent via modem.transmit, and the receiving computer repackages it as a rednet event at the other end (within rednet.run, which runs in parallel with the shell on all systems whether you ask for it or not - including those which don't have modems connected at all).
Prior to CC 1.6, there's no table encapsulation - the message just gets modem.transmit'd more or less as-is, and rednet.run thus has a slightly more simplistic job.

Alright, so as I interpreted, it sends a table? Thank you! That helps me a lot
