System Maintenance & Information

The BootModule AT commands execute from within the router’s bootup software, when debug mode is
selected before the main router firmware (ZyNOS) is started. When you start up your ZyWALL, 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

Transferring Files chapter.

Enter 

ATHE

 to view all available ZyWALL 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; e.g., 

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.
