Hm... It is a while since I did one of these and I think your problem 
appears to be one of choosing the correct terminal emulation rather than 
fiddling with scroll buffers. On my system if I do a sh/co/no, I get this:

Which according to 'wc -l' is 84 lines long. So fiddling with the size 
of the scroll buffer won't help. On my copy of putty running on windows 
xp (logged in either as a telnet client or via ssh and running 
console.pl) the scrolling works correctly using standard parameters.

Could the changes that you have made caused this? Send me a 'diff -u 
/spider/perl/console.pl /spider/local' and the same for Console.pm.
