	-L, --lin1=arg       move polaroid linear stage to N steps
	-R, --rot1=arg       rotate polaroid to given angle
	-S, --stop           stop any moving
	-a, --sendraw=arg    send RAW string to port and read the answer
	-b, --baudrate=arg   TTY baudrate
	-d, --comdev=arg     terminal device filename
	-h, --help           show this help
	-l, --lin2=arg       move waveplate linear stage to N steps
	-p, --pidfile=arg    PID-file name
	-q, --quiet          don't show anything @screen from stdout
	-r, --rot2=arg       rotate lambda/4 to given angle
