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, change this value from zero (0) to the maximum lines.
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.
By default, the Scroll History will be cleared whenever a "clear screen" command is received from the host -- this can be changed and all screens can be scrolled using the Scroll Cleared Screen Lines setting.
Once a scroll-history is active, the client can clear the history by opening the Settings and clicking on the "Clear History" button.
In a Profile, this value can be inherited from a linked, parent profile. The Track Marks (
) will indicate if the value is default, from the parent Profile or unique to this profile.
