How to Increase the Scrollback Buffer in PuTTY

At a recent Cisco ASA training workshop, one of the students asked how to increase the buffer size in PuTTY so he could see more output history. Here's how to do it:
  1. In the PuTTY configuration window, select Window in the category tree on the left.

  2. Change the Lines of scrollback to whatever value you wish. The default is 200. Some people set it as high as 5000.
  3. If you'd like to make the new setting the default, select Session in the category tree, in the Saved Sessions window, type Default Settings, and click Save.
