speaking of ng_tty... it is clear to me how to inject data into Netgraph
in a safe way, but it is not yet clear how Netgraph can inject data into
other subsystems.

you see, the Bluetooth spec defines several Host (PC) to Host Controller
(Bluetooth unit) communication protocols. one of them is UART transport
layer (AKA H4). i have implemented H4 line discipline that also a
node. (i called it ng_sio in my report but it was wrong). it works now,
and i can talk to Xircom card, but it should be changed later. any
