Serial Port sending one byte during opening #12

I tried the serial port on Rpi to run expEYES and everything is working fine. Whenever the '/dev/ttyAMA0' is opened , one byte (value = 0xF8) is send to the connected device. I just added a work around in the expEYES code on the uC. The code used for testing it is attached. The byte send is tracked on the uC end using a debugger.
