  read data coming from bridge using the Console.read() function
  and store it in a string.
  
+ To see the Console, pick your Yun's name and IP address in the Port menu
+ then open the Port Monitor. You can also see it by opening a terminal window
+ and typing 
+ ssh root@ yourYunsName.local 'telnet localhost 6571'
+ then pressing enter. When prompted for the password, enter it.
