  -R, --readc            registers (by keycodes, checked by dictionary) to read; multiply parameter
  -W, --writec           write new value to register by keycode (format: keycode=val); multiply parameter
  -b, --baudrate=arg     modbus baudrate (default: 9600)
  -d, --device=arg       modbus device (default: /dev/ttyUSB0)

  -o, --outfile=arg      file with parameter's dump
  -r, --readr            registers (by address) to read; multiply parameter
  -s, --slave=arg        slave ID (default: 1)
  -t, --dumptime=arg     dumping time interval (seconds, default: 0.1)
  -v, --verbose          verbose level (each -v adds 1)
