Side note: I'm intend to revert some API changes on trunk version about slave ID.

but currently modbus_slave_manage() uses the slave ID defined in modbus_param (trunk version of libmodbus):

void modbus_slave_manage(modbus_param_t *mb_param, const uint8_t *query,
                         int query_length, modbus_mapping_t *mb_mapping)
{
       ....

        if (slave != mb_param->slave && slave != MODBUS_BROADCAST_ADDRESS) {
