SYNOPSIS

       int modbus_set_debug(modbus_t *ctx, int flag);


DESCRIPTION

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