Re: ioctl() not implemented

[Andrea Pacini <pacionet at email dot it>]

I am not very expert, anyway fd is:
   
     [..]
      fd = open(siodev, O_RDWR | O_NONBLOCK);
    [...]
    if (fd == -1) err(1, "can't open slipdev");
  }

where siodev is the string "/dev/ttyS4" (the open seems work because
there are no error messages).
How I should use SetCommState ?

Thanks a lot
Andrea
