I have included a code snippet below that I used for checking 7 bits. And the code returns true for the if condition which doesn't make sense.The code works fine for parity setting but not for databits settings. What could be the reasons for this problem?"

tios.c_cflag |= CS7;
tios.c_cflag |= PARENB;

databits = tios.c_cflag & CSIZE;
	if(databits==CS8){
	fprintf(stderr,"No of bits per byte is 8 %x\n",databits);
	}
