The scroll action will spread across the line, and down a multi-line wall (just set a new, different channel on the first row you want to exclude), and will continue until "stop_scroll" or any displayable message is received. * "start_scroll" starts the automatic scrolling function, repeatedly moving the last displayed message to the left one character space each time the scroll timer runs out (and automatically restarting it, natch).

* "stop_scroll" does just what it says - it stops the auto-scroll timer. As it advances through the message, the scroll code will search through the message for a printable character, on each scroll step, basically stripping-out color code, and using just the last one before the new start position. This is done in order to keep a constant visible speed (the text will still be colored properly though).

The "master"/connected panel stores the last-displayed message and some other details in its metadata, so you may occasionally need to dig and re-place the panel if things go wonky (this won't happen during normal use, but it may happen if you're making lots of changes to the panels' layout, channel names, etc) The "master"/connected panel stores the last-displayed message and some other details in its metadata, so you may occasionally need to dig and re-place the panel if things go wonky (this won't happen during normal use, but it may happen if you're making lots of changes to the panels' layout, channel names, etc).
