File Transfer and Error Recovery
R.L. Sunberg · 1971
Handshaking I think that Mr Bhushan(RFC #114, NIC 5823) is not strict enough in his concept of a transaction sequence.Every transaction should prompt a response from its recipient (recall Kalin's crates --RFC #60, NIC 4762).Control should pass back and forth until the server terminates.The server _always_ gets the last word (more on error recovery later).Some sample interchanges are given.
