No, but using serport.c, you can bind a serio to a tty via a line discipline, for example if you want a PC serial mouse on /dev/ttyS0 to talk to sermouse.c via serio. I don't like the approach much, I hope(d) we could switch somewhere below the tty layer, but it sort of works, and maybe will have the bugs fixed sooner or later.
So how about this:
1) When SERIO device is claimed, we fail of TTY copy is opened by any user.
2) Once we allow SERIO device to be claimed, we prevent opens of TTY copy.
I guess this is sort of what Russell is recommending. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
