[Ftdi-usb-sio-devel] [SOLVED] Baudrate setting is broken.

[Teunis v. B. <te...@gm...>]

Dear maintainers,

It looks like I solved the problem.

I was using this code to set the params for the serial port:

  new_port_settings.c_cflag = baudr | cbits | cpar | bstop | CLOCAL | CREAD;
  new_port_settings.c_iflag = IGNPAR;
  new_port_settings.c_oflag = 0;
  new_port_settings.c_lflag = 0;
  new_port_settings.c_cc[VMIN] = 0;      /* block untill n bytes are received */
  new_port_settings.c_cc[VTIME] = 0;     /* block untill a timer
expires (n * 100 mSec.) */
  cfsetispeed(&new_port_settings, baudr);
  cfsetospeed(&new_port_settings, baudr);
  error = tcsetattr(Cport[comport_number], TCSANOW, &new_port_settings);

After adding the next two lines to my sourcecode, it works fine:

cfsetispeed(&new_port_settings, baudr);
cfsetospeed(&new_port_settings, baudr);

So, this means that setting the baudrate with:

new_port_settings.c_cflag = baudr | cbits | cpar | bstop | CLOCAL | CREAD;

is not sufficient??

(baudr is an int that contains the value B9600 or B19200, etc.)

Sorry for bothering,

Best Regards,

Teunis van Beelen
