Hmm.. As I wrote, netgraph is good framework for my driver. Now I
see only one problem: I need to change speed of COM port from my
driver (all setup of device should be done at 9600 and after that
link could be switched to other, negotiated, speed like 115200).
If I use ng_tty or my own NG node, which acts as TTY discipline, I
don't see way to change COM port speed from this side :(
