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.
