Ups, oh yeah. It should be
    _uarts[uart].regs->conf0.stop_bit_num = 1;
    _uarts[uart].regs->rs485_conf.dl1_en = 0;

This happened propably when I changed it back from trying to remove the hack due to the hardware bug. I thought that it is not necessary to test it again since it worked before :sunglasses:
