A tool that enters the Honeywell boot loader via Dimension / G3 RS232 port on boot. The Galaxy boot loader has a menu option to dump or write to memory in double words. The tool holds a list of address locations where the passwords are held (different firmware versions hold the codes and passwords at different offsets), or can also scan all of memory for them which takes longer. Since these codes and passwords are plain text in memory, it can read them out or clear them. To enter the boot loader, it does need the panel to be rebooted, so not a back door that compromises the panel. You can do it all manually from TTY, but it would take an age, so the program speeds things up.
