Both CCI server and CCI client applications need to have a Server Name specified: server applications need to register themselves as available under this name (or what fixed port to use); and clients need to specify which server they wish to contact. This can be any valid alphanumeric string (up to 14 characters in length). Strings must be terminated with either a space (" ") or a NULL (binary zero) byte. Names presented with a length greater than this limit will be rejected with a bad parameter message, to avoid the possibility of a truncated name allowing connection of a client to an unwanted service.
