[En-Nut-Discussion] Bug in half duplex mode

[Szemző András]

Hi Harald,

Thanks your reply, but I saw the CVS log. I using it now, but I still have
problems.

I'm very new in Ethernut (yet), so I thing I miss something.
If I compile ethernut with HDX bit setup, then in the app I still need
tenable flow controll, like this, or it's not nessesary. 

foo = USART_MF_HALFDUPLEX;
_ioctl(_fileno(uart), UART_SETFLOWCONTROL, &foo);


If yes, I was a lamer and sorry for disturbing.

Thanks,

Best Regards,
Andras
