[ydl-gen] Scroll lock in terminal mode?

[jekillen]

Hello;
I am running YDL 3.0 on a Mac 3400c Powerbook. I use it
for backup DNS  server for my web sites. Since that is all
it really does, now, I have it running 24/7 in terminal mode.
I would like to do 'cat access_log | tail -100' to see the
latest and greatest hits. I have a placeholder web site
running on it and someone has taken to overloading it
with what look like pings ("-" "-"). It has been eating up
the memory (only has 144Mb max) and it is killing httpd
processes, and sendmail process. So I reboot, and since
I don't really need Apache running I shut it down. But I
need to do some sleuthing and maybe set some hosts.deny
rules.

I don't know how to clear the display or do scroll lock so I
can see what is above the actual display. Does anyone know?
Thanks in advance.
JK
