pkon, pkoff - establish packet protocol
Pkon establishes packet protocol (see pk(4)) on the open character special file whose file
descriptor is fd. Size is a desired packet size, a power of 2 in the range
32<=size<=4096. The size is negotiated with a remote packet driver, and a possibly
smaller actual packet size is returned.
An asynchronous line used for packet communication should be in raw mode; see tty(4).
Pkoff turns off the packet driver on the channel whose file descriptor is fd.
pk(4), pkopen(3), tty(4), signal(2)
Pkon returns -1 if fd does not describe an open file, or if packet communication cannot be
Pkoff returns -1 for an unknown file descriptor.
Writing on a packet driver link that has been shut down by close or pkoff at the other end
raises signal SIGPIPE in the writing process.
