I think I have found a bug in kl5kusb105.c. I am using 2.6.0. I tried to use a few lines of the kl5kusb105.c code in my own driver and it didn't work. This was what I took:
Line 994:
if (user_termios_to_kernel_termios(&priv->termios,
(struct termios *)arg))
return -EFAULT;
klsi_105_set_termios(port, &priv->termios);The problem here is, that this puts the new termio settings into priv->termios and gives that to klsi_105_set_termios as the old_termios parameter. That means, that all changes are discarded. I now use this instead and it works for me:
if (user_termios_to_kernel_termios(&termios,
(struct termios *)arg))
return -EFAULT;
memcpy(port->tty->termios,&termios,sizeof(struct termios));
saal_set_termios(port, NULL);So I copy the new termios to port->tty->termios so that set_termios sees them as the new termio settings. I am now running a serial terminal attached to my usb serial converter. Perhaps one should also save the old settings from port->tty->termios and give that to set_termios as the
old_termios parameter, but my set_termios doesn't currently use it.
Any comments? Did you allready know this?
Regards Alexander
