Custom device types and icons

Thanks, Paul (phands)!  Someone needed to take this into their own hands because Netgear seems to have been letting this languish for at least a couple years.

I follow your description of what you did and how one would modify the existing device type images (icons) and add new ones.  I'm not uncomfortable using command line interfaces, and I think I can salvage enough vi from the deep recesses of my brain to make the needed edits.  I would, however, benefit substantially if you would elaborate on how to

1. enable telnet access "from the hidden debug page" and
2. properly launch telnet (using the telnet client in Windows, say) to the router with admin privileges.
