So I've got a console that I'd like to run as a server, and several other consoles that I'd run as a client. Each have modems connected, and I've checked all ID's of all computers. The idea is you log in to a computer and then it opens the door (A more complex variation of the password-protected doors). The problem is after I've got the server up and running, and the client up and running, the client will always give me a "Not Authorised" message (an error message that I write client-side).
If anyone could tell me why I'm getting the error message that'd be perfect. Below is the code, let me know if I need to provide any more details. Also, the Client doesn't have any door-opening code in it, because that code is quite trivial and easy to do.
Eventually it'll be set up so that certain doors have permission levels, so only Administrators can enter the server room, etc.
