-\cfg{winhelp-topic}{ssh.bugs.winadj}
-
-PuTTY sometimes sends a special request to SSH servers in the middle
-of channel data, with the name \cw{winadj@putty.projects.tartarus.org}
-(see \k{sshnames-channel}). The purpose of this request is to measure
-the round-trip time to the server, which PuTTY uses to tune its flow
-control. The server does not actually have to \e{understand} the
-message; it is expected to send back a \cw{SSH_MSG_CHANNEL_FAILURE}
-message indicating that it didn't understand it. (All PuTTY needs for
-its timing calculations is \e{some} kind of response.)
-
-It has been known for some SSH servers to get confused by this message
-in one way or another \dash because it has a long name, or because
-they can't cope with unrecognised request names even to the extent of
-sending back the correct failure response, or because they handle it
-sensibly but fill up the server's log file with pointless spam, or
-whatever. PuTTY therefore supports this bug-compatibility flag: if it
-believes the server has this bug, it will never send its
-\cq{winadj@putty.projects.tartarus.org} request, and will make do
-without its timing data.
