13.7.2 Uploading ROM File
The configuration, system-related data, the error log and the trace log are all stored in the ROM
file system. Menu 24.7.2 shows you the instructions for uploading ROM file. Please be aware
that uploading the ROM file replaces everything contained within. If you answer yes to the
prompt, the Prestige will reboot automatically. Press any key when you see the message “Press
Any key to enter Debug Mode within 3 seconds.” to enter debug mode.
Once in debug mode, type [atur 3 ] and wait for your Prestige to respond with “Starting
XMODEM upload” to begin uploading the ROM file (uploading procedure varies depending on
the software used). After successfully uploading the ROM file, type
atgo to restart your Prestige.
If you upload the default ROM file, you will lose all configuration that you had before and the
console port will be set to the default of 9600 baud. You will need to change the baud rate of your
serial communications software to 9600 before you can connect to the Prestige again.
