Hm, I saw this but didn’t get it - what is “a sequence of commands resulting in 
a SEND” (or RECEIVE) ?
I just don’t get what that’s supposed to mean. E.g., what else than SEND will 
send?

I also saw this but didn’t see it as mandatory to provide (“It may be useful…”, 
the text says). Is this really very useful?

Nothing that’s not in the RFCs… I did rephrase the authentication stuff for TCP 
as “CONNECTION.MAINTENANCE” primitives (set_auth, get_auth), stating that 
they’d be implemented using SEND and RECV. Not much else available…

If you say it’s important it can be added, I guess, but I find it hard to 
derive that from the text in RFC 5925. Well, empty send’s and receive’s are a 
way out, I suppose.

Cheers,
Michael
