This is a really simple application which just displays rednet messages and allows you to send them. This is useful for reverse-engineering things, or for testing your own things.

Usage:
  • Install it (command: 
    pastebin get vprpZUjZ
    , link)
  • Answer the prompts for a protocol, sender and receiver (these only affect messages you send). If you just hit enter, they will default to nil, your computer's ID and the broadcast channel respectively.
  • Type in messages. They will be sent (as strings) to the given receiver, spoofing the given sender, with the given protocol (if it's nil, they should be sent with no protocol).
  • Watch messages be sent.
