       The modbus_get_response_timeout() function shall return the timeout interval used to wait for a response
       in the to_sec and to_usec arguments.

           uint32_t old_response_to_sec;
           uint32_t old_response_to_usec;

           /* Save original timeout */
           modbus_get_response_timeout(ctx, &old_response_to_sec, &old_response_to_usec);

           /* Define a new and too short timeout! */
           modbus_set_response_timeout(ctx, 0, 0);
