[comp.protocols.tcp-ip] BSD 4.3 Terminates zero window connection

geof@imagen.UUCP (Geof Cooper) (11/20/87)

A customer has reported that BSD4.3, if it is presented with a zero window,
tries ONCE to push data through the window.  If it receives no response,
it closes the connection.  There is a language problem between me the
customer and the manuals, so maybe I don't understand what they are
saying.  Does this match 4.3 behavior?

This is not true in general, and I don't know of any bugs in this area
that cause connections to close when the window closes.  There was a bug
in 4.2 that could cause connections to close if the window was retracted
after data had been sent into it; I believe that this is fixed in 4.3BSD
as well, although I didn't take the time to set up a situation in which
to test that.
