How completely clear screen using putty?

[apple01]

I taught a basic UNIX class about 8 years ago using straight Telnet to connect. My school has asked me to teach it again. Not only am I very rusty, but now I have to use putty to connect. I have not been able to figure out how to CLEAR the entire buffer. When I issue the "clear" command the current screen gets cleared, but if I scroll back the old data is still there. I'd like to clear the whole buffer. I found a putty setting talking about "scrollback" but nothing I've tried works. Any suggestions?
Thanks,

It's been a number of years since I used Putty but I seem to recall that there is a "Terminal" tab or menu entry which should have a "Reset and Clear" option (or something like that), which should clear the screen as well as the scrollback buffer.

Haven´t tested it, but if you set "Lines of scrollback" in the "Window" section to zero, then there shouldnt be anything there.
Hence: No old data

Thanks RM. Unfortunately, I did not find the kind of setting you're talking about on the puTTY software I downloaded.

Thanks Irithori. Looks like that works. However, I want to be able to have my cake and eat it to I' like having 200 lines to go back to, I'd just like to be able to clear it all when I want to.
