Answer 1

I was just giving a try for max lines on windows 7 i can set using mode con command and found it to be 32766 2^15-2 and you can set it with following command

mode con lines=32766

although you can set screen buffer size from the GUI too, but the max you can get is 9999.

Answer 2

I have found a way to resize the buffer size without influencing the window size. It works thanks to a flaw in how batch works but it gets the job done.

mode 648 78 >nul 2>nul

How does it work? There is a syntax error in this command, it should be "mode 648, 78". Because of how batch works, the buffer size will first be resized to 648 and then the window resize will come but it will never finish, because of the syntax error. Voila, buffer size is adjusted and the window size stays the same. This produces an ugly error so to get rid of it just add the ">nul 2>nul" and you're done.
