If your ASCII protocol host displays screens that have line scrolling "off the top" and your users would like these to be saved in the browser, add this setting to your web.config.
Once activated, any lines scrolled up will be saved in a scroll-history HTML section--when this occurs, the emulation area will have a vertical scroll-bar added to the right and the fonts will resize slightly to accommodate the scroll-bar. Stretching fonts is recommended for the best appearance when the scrolling history is active.
Once a scroll-history is active, the client can clear the history by opening the Settings and clicking on the "Clear History" button.
