Serial communication Problem using arduino MEGA 2560

I am using Arduino MEGA 2560 for serial communication. I am using MATLAB for the coding for the same.

After configuring and downloading the code in the board, I am trying to receive data using Real term software. The problem is, sometimes I am receiving the correct data and sometimes I am not even if I am sending the same data.

I don't understand what is the problem. I am attaching screenshot of data i am receiving in both the cases. Serial Communication details: baud rate: 115200 datatype: uint16 Board to PC interface: UART to USB converter

Can anyone help with this?? </matlabcentral/answers/uploaded_files/49853/arduino_serial_problem1.jpg>

I solved the problem by breaking my uint16 data into 2 byte and sending successfully through serial port.
