In your pc you will be able to read the ModBus registers using an application like ``mbpoll``::
$ mbpoll -a 10 -b 38400 -t 3 -r 1000 -c 4 /dev/ttyUSB1 -R
modbus_master
-------------
Configures the ModBus RTU Master located at apps/examples/modbusmaster. This
configuration enables a RS485 on USART6.
After configuring the desired pins on menuconfig and wiring the RS485 converter, you
can enable the ModBus Master to create queries for device with address 10::
nsh> mbmaster
In your pc you will be able to create a ModBus Slave with address 10 using an application like ``diagslave``::
$ sudo diagslave -a 10 -b 38400 /dev/ttyUSB0
