scp is a simple, but poorly documented, protocol. Thankfully, its source is

well.

resource, but has some bad information. Its first problem is that it doesn't
correctly describe why the producer has to read more responses than messages
it sends (because it has to read the 0 sent by the sink to start the
transfer). The second problem is that it omits that the producer needs to
send a 0 byte after file contents.
