Issue reading COM port data (MATLAB 2015a)

I have connected my sensor output to an Arduino and its output through a USB cable to COM Port. I tried the following code in MATLAB

===================================

s=instrhwinfo('Serial');

s.AvailableSerialPorts

===================================

and observed that MATLAB does detect my COM Port successfully.

Then I defined my serialPort and then I tried the following code

===================================

board = serial(serialPort, 'BaudRate', 115200, 'FlowControl','None');

fopen(board);

S = fscanf(board)

===================================

I am just getting one line message that reads

Initializing I2C devices...

Whereas I expect a three line message where the third line asks for any key-press to continue.

When I execute the following line again

S = fscanf(board)

I get the second line and then the third line when I run the code again

After that I get the following error

Warning: Unsuccessful read: A timeout occurred before the Terminator was reached..

S =

     ''

When I do that it Hyper-terminal, it does work as expected. My requirement is to see the same data which I get in Hyper Terminal to be ready here in MATLAB Command window.

Please help.
