DESCRIPTION

12       The modbus_set_debug() function shall set the debug flag of the
13       modbus_t context by using the argument flag. By default, the boolean
14       flag is set to FALSE. When the flag value is set to TRUE, many verbose
15       messages are displayed on stdout and stderr. For example, this flag is
16       useful to display the bytes of the Modbus messages.
