comes up.
+\S{config-logflush} \q{Flush log file frequently}
+
+\cfg{winhelp-topic}{logging.flush}
+
+This option allows you to control how frequently logged data is
+flushed to disc. By default, PuTTY will flush data as soon as it is
+displayed, so that if you view the log file while a session is still
+open, it will be up to date; and if the client system crashes, there's
+a greater chance that the data will be preserved.
+
+However, this can incur a performance penalty. If PuTTY is running
+slowly with logging enabled, you could try unchecking this option. Be
+warned that the log file may not always be up to date as a result
+(although it will of course be flushed when it is closed, for instance
+at the end of a session).

\S{config-logssh} Options specific to SSH packet logging
These options only apply if SSH packet data is being logged.
turn this option off and make PuTTY only use the default foreground
and background colours.
+\S{config-xtermcolour} \q{Allow terminal to use xterm 256-colour mode}
+
+\cfg{winhelp-topic}{colours.xterm256}
+
+This option is enabled by default. If it is disabled, PuTTY will
+ignore any control sequences sent by the server which use the
+extended 256-colour mode supported by recent versions of \cw{xterm}.
+
+If you have an application which is supposed to use 256-colour mode
+and it isn't working, you may find you need to tell your server that
+your terminal supports 256 colours. On Unix, you do this by ensuring
+that the setting of \cw{TERM} describes a 256-colour-capable
+terminal. You can check this using a command such as \c{infocmp}:
+
+\c $ infocmp | grep colors
+\c colors#256, cols#80, it#8, lines#24, pairs#256,
+\e bbbbbbbbbb
+
+If you do not see \cq{colors#256} in the output, you may need to
+change your terminal setting. On modern Linux machines, you could
+try \cq{xterm-256color}.
+
\S{config-boldcolour} \q{Bolded text is a different colour}
\cfg{winhelp-topic}{colours.bold}
