Appendix D
Boot Commands
The BootModule AT commands execute from within the router’s bootup software, when
debug mode is selected before the main router firmware is started. When you start up your
Prestige, you are given a choice to go into debug mode by pressing a key at the prompt shown
in the following screen. In debug mode you have access to a series of boot module commands,
for example ATUR (for uploading firmware) and ATLC (for uploading the configuration file).
These are already discussed in the
Firmware and Configuration File Maintenance chapter.

Enter ATHE to view all available Prestige boot module commands as shown in the next
screen. ATBAx allows you to change the console port speed. The x denotes the number
preceding the colon to give the console port speed following the colon in the list of numbers
that follows; for example ATBA3 will give a console port speed of 9.6 Kbps. ATSE displays
the seed that is used to generate a password to turn on the debug flag in the firmware. The
ATSH command shows product related information such as boot module version, vendor
name, product model, RAS code revision, etc. ATGO allows you to continue booting the
system. Most other commands aid in advanced troubleshooting and should only be used by
qualified engineers.
