This changes from a line discipline to the tty_hooks mechanism. Data will come in directly via rint_bypass and sent to the peer node in a single mbuf. As line disciplines are no longer used a new netgraph command called NGM_TTY_SET_TTY is used to attach the tty. This takes a pointer to to the open file descriptor of the tty and registers the tty hooks. When the tty disappears the node will shutdown. Thanks to: ed Sponsored by: Hobnob, Inc
