Simple CLI control tool allowing bash scripting 
===============================================


## Command line arguments

- `-A, --absmove`--      absolute moving, use this flag to point that steps amount (parameters of `-L`, `-l`, `-R` or `-r`) are given in absolute position (without this flag steps meaning as relative);
- `-E, --reset`--`       reset given mcu (may be included several times), each `-Ex` (where `x` is controller ID) will send signal to reset given MCU;
- `-L, --lin1=arg`--     move polaroid linear stage to N steps;
- `-R, --rot1=arg`--     rotate polaroid to given angle (angle in degrees);
- `-S, --stop`--         stop any moving (with this flag each MCU will receive a signal to stop any moving);
- `-a, --sendraw=arg`--  send RAW string to port and read the answer, if you want to send something that can't be reached by standard arguments, use this flag;
- `-b, --baudrate=arg`-- TTY baudrate (raw number, e.g. 115200), default speed is 9600;
- `-d, --comdev=arg`--   terminal device filename, default path is `/dev/ttyUSB0`;
- `-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
- `-s, --status`--       get device status
- `-t, --temp`--         show temperature of both MCU
- `-w, --wait`--         wait while all previous moving ends
- `-y, --async`--        asynchronous moving - don't wait
