[En-Nut-Discussion] Baud 19200 Rs232 port

[Cosmin Buhu]

    And what OS version? 3.4.3 has baudrate IOCTL support
for debug (3.4.2 hasn't) .

I think cause your using the debug port.

Try

NutRegisterDevice(&devUsartAvr0, 0, 0);
g_rs232 = fopen("uart0", "r+b");
fileno = _fileno(g_rs232);
lTmp = 9600;
    _ioctl(fileno, UART_SETSPEED, &lTmp);

I try to communicate throuth the rs232 port on the ethernutboard. I want the
baudrate to be 19200. I have written this:

main(){
    u_long baud = 19200;
    u_char i = 0;
   FILE *uart;

// Initialize UART
    NutRegisterDevice(&devDebug0, 0, 0);
    freopen("uart0", "w", stdout);
    _ioctl(_fileno(stdout), UART_SETSPEED, &baud);
    NutSleep(200);}

I write to the rs232 port by using the "printf" command, but when i use the
Terminal program I only get words by using the 115200 baud. It happens
nothing when i use 19200 baud.

Is it something I write wrong, or is it any other variables i have to change
to get baud 19200? What about stopbits and handshake?

Thank you!
Sigurd Kleppan
