Hi,

Thanks for the reply!

What I cant see from that is how one can avoid touching userspace at all
- as far as I can see, only userspace can actually attach a line
discipline to a serial port. I'd like to have this happen in the kernel
so that I dont need some program sitting idly opening the serial device
the whole time.

Thanks,

-Ian!
