IBM M71V2 manual Journaling File System, rm -rf

Journaling File System

The M71V2 Handheld terminal includes the capability to save programs and data. There is a special, non-volatile sub-directory to store user information. This sub-directory is jffs2 (lower case only) and can be accessed from the Linux prompt by typing “cd jffs2”. You can list the contents of this directory by typing “ls” (list).

The jffs2 subdirectory contains all the customer supplied setup files. It is possible to completely reset the terminal back to factory defaults by issuing this command while in the jffs2 subdirectory:

rm –rf *

This command will clear all of the user’s settings, do not use this command unless a complete reset is required.

You can quickly setup multiple units to have exactly the same settings by copying (FTP’ing) the settings.xxxxxx files to other units. Remember that the RF settings are included in these files and it is possible to get duplicate IP addresses on the network by copying these files. These files also include the WEP settings, which may, or may not, be correct for your network.

FTP

You can easily upload and download to the M71V2 Handheld terminal over the RF link, by using a File Transfer Program (FTP). These programs are readily available over the Internet. In order to communicate with the M71V2, it must be turned on, and you must know its current IP address. Most FTP programs require you to supply a User Name and Password for the connecting device.

The default user name is “aml” and the default password is “turk182”

(case sensitive).
