To install a new version:
1. Ensure that image transfers are enabled on the Upgrade
Software screen. The image currently not running will be the
image replaced by the upgraded software.
2. Run the DOS program “tutxlutil” from the diskette provided
by Tut Systems on a PC connected to the LAN to which the
modems are connected (refer to page 46, “Detailed Steps for
Running Tutxlutil”).
3. When a new image has been successfully received, the display
will change to indicate its version, along with the notation
[untried], which indicates that the modem has not yet tried to
boot this image.
4. Change “Choose Image to Boot” to the new [untried] image
and press <Enter> to accept the new settings.
5. Select “R” from the Main Menu and reboot the modem. When
the modem restarts, the Upgrade Software screen will show that
the new image is running, and the [untried] notation will be
gone. Use the Upgrade Software screen once more to verify
that the new image is running.
If the modem does not restart after a minute, power cycle the
modem by unplugging the unit and plugging it in again. It will now
boot the old image, and the new, unsuccessful image will be marked
[failed to boot]. Depending on the failure, the modem may reboot
itself automatically, using the old image.
To return to the Main Menu without changing any settings, press
<Ctrl-X>.
