All is good. But when I try to write: 
system("echo -e "\xFF\x08\x00" >> /dev/ttyACM0");

It gives me syntax error. Do you guys have any idea why this is happening, and how I can espace this so that the command works? I suspect that the \x00 is a null byte that is terminating the command , thus the error. But how to fix?
