/*! \example modbus/custom
\title Modbus Custom command example
\brief The example implements a Modbus client-server application.
The example acts as both Modbus client and server in a single application.
The connection between them is established via Modbus TCP. It is used to
send and receive custom Modbus requests and adjusts its internal states
based on the request and response.

\include examples-run.qdocinc
This example cannot be used in conjunction with other applications. Once the
example is started, it can only exchange custom Modbus commands within the
application itself. All interactions between the client and server use the
Modbus TCP protocol.
The main purpose of the example is to provide some demo code on how to
implement a Modbus client or Modbus server handling custom Modbus function
codes.
