    usage : mbpoll [ options ] device|host [ writevalues... ] [ options ]
    
    ModBus Master Simulator. It allows to read and write in ModBus slave registers
                             connected by serial (RTU only) or TCP.
    
    Arguments :
      device        Serial port when using ModBus RTU protocol
                      COM1, COM2 ...              on Windows
                      /dev/ttyS0, /dev/ttyS1 ...  on Linux
                      /dev/ser1, /dev/ser2 ...    on QNX
      host          Host name or dotted IP address when using ModBus/TCP protocol
      writevalues   List of values to be written.
                    If none specified (default) mbpoll reads data.
                    If negative numbers are provided, it will precede the list of
                    data to be written by two dashes ('--'). for example :
                    mbpoll -t4:int /dev/ttyUSB0 -- 123 -1568 8974 -12
    General options :
      -m #          mode (rtu or tcp, TCP is default)
      -a #          Slave address (1-255 for rtu, 0-255 for tcp, 1 is default)
                    for reading, it is possible to give an address list
                    separated by commas or colons, for example :
                    -a 32,33,34,36:40 read [32,33,34,36,37,38,39,40]
      -r #          Start reference (1 is default)
      -c #          Number of values to read (1-125, 1 is default)
      -u            Read the description of the type, the current status, and other
                    information specific to a remote device (RTU only)
      -t 0          Discrete output (coil) data type (binary 0 or 1)
      -t 1          Discrete input data type (binary 0 or 1)
      -t 3          16-bit input register data type
      -t 3:hex      16-bit input register data type with hex display
      -t 3:int      32-bit integer data type in input register table
      -t 3:float    32-bit float data type in input register table
      -t 4          16-bit output (holding) register data type (default)
      -t 4:hex      16-bit output (holding) register data type with hex display
      -t 4:int      32-bit integer data type in output (holding) register table
      -t 4:float    32-bit float data type in output (holding) register table
      -0            First reference is 0 (PDU addressing) instead 1
      -B            Big endian word order for 32-bit integer and float
      -1            Poll only once only, otherwise every poll rate interval
      -l #          Poll rate in ms, ( > 100, 1000 is default)
      -o #          Time-out in seconds (0.01 - 10.00, 1.00 s is default)
    Options for ModBus / TCP :
      -p #          TCP port number (502 is default)
    Options for ModBus RTU :
      -b #          Baudrate (1200-921600, 19200 is default)
      -d #          Databits (7 or 8, 8 for RTU)
      -s #          Stopbits (1 or 2, 1 is default)
      -P #          Parity (none, even, odd, even is default)
      -4            RS-485 mode (/RTS on after sending)
      -5            RS-485 mode (/RTS on when sending)
    
      -h            Print this help summary page
      -V            Print version and exit
      -v            Verbose mode.  Causes mbpoll to print debugging messages about
                    its progress.  This is helpful in debugging connection...
