[Dxspider-support] Increasing size of scrollback buffer in sysop console

[Martin Davies G0HDB]

Hello all, I hope everyone had an enjoyable Christmas and is rarin' to go in 2016!

I regularly use the sysop console on my GB7DXC-5 node (running on a headless Raspberry 
Pi so all accesses are via puTTY and SSH) and have wondered for a while how to increase 
the size of the console's scrollback buffer so that I can see, for example, the complete listing 
of a 'sh/co/no' command.  Currently when I do this I can't scroll back to the start of the listing 
because the start of the list disappears under the 'system' messages in what I understand is 
the defined as the 'top screen'.  

I know I could set the page length to enable me to see the listing approx 60 lines at a time, 
but I would much prefer to be able to scroll back as far as I need to.

I run the 'local' version of console.pl that's in /spider/local, to avoid tampering with the 
released version that lives in /spider/perl, and I've already made a couple of minor changes to 
the local version of Console.pm to alter some of the fonts used by the console, but because 
of my unfamiliarity with PERL I can't see which variable(s) to change to alter the size of the 
scrollback buffer so I'll be very grateful for any help and guidance.

Thanks in advance, and HNY when it comes.
