I have only been working with RISCOS plink, and there doesn't
seem to be an option for it. Are you talking about a command
to send to the destination/server who would keep it alive.
I haven't used Putty on other platforms, and haven't seen the
format of a session file yet.
What are the details of the keepalive then?
If port forwarding I imagine it would be best sending something
to the end recipient.

I haven't been working with OpenSSH client/server but will have
a read sometime.
