Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "You can access the Cloud9 integrated development environment (IDE) from the Start.html link on the microSD card image."

A block of code is set as follows:

<html>
  <head>
    <title>Wireless Hub Access Page</title>
  </head>
  <body>
  <h1>Here is a simple way of accessing your Router via Yaler:</h1>
 

        <a href="http:192.168.10.1"> Here is my Router Page </a>

  </body>
</html>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

var outputPin1 = "P8_13";        //Alarm Output 1
var outputPin2 = 'P8_11';        //Alarm Output 2
var outputPin3 = 'P8_12';        //Alarm Output 3
var outputPin4 = 'P8_14'; //Alarm Output 4

Any command-line input or output is written as follows:

$ mkdir yalertunnel
$ cd yalertunnel

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Navigate to Connection | Data and set Auto-login username to root."
