Appendix G Boot Commands; Figure 272 Option To Enter Debug Mode - ZyXEL Communications P-870HW-I Series User Manual

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
ZyXEL Device, 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.

Figure 272 Option to Enter Debug Mode

Enter ATHE to view all available ZyXEL Device 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.
