[En-Nut-Discussion] uart configuration

[ChouK]

thanks for your answer but what do you mean by "that the lines were 
connected to the D-Sub plug". my card is the ethernut 2.1b and I don't find any sub plug.
look for my jumper configuration on jumperConfig.jpg.
regards,
Nicolas

Hello,

I did it like this:

#include 
[...]
int main(void)
{
[...]
NutRegisterDevice(&devUsartAvr0, 0, 0);
freopen("uart0", "r", stdin);
freopen("uart0", "w", stdout);
unsigned long baud = 115200;
_ioctl(_fileno(stdin), UART_SETSPEED, &baud);
_ioctl(_fileno(stdout), UART_SETSPEED, &baud);
fprintf(stdout, "stdout is routed here...\n");
[...]
}

Don't know if you (and I :)) need both the _ioctl() calls...

And I had to check the jumper configurations, so that the lines were 
connected to the D-Sub plug, I found this in the Hardware Manual that 
came along with the card...

Hope it helps...

Arnfinn
