Upgrade Instructions
To upgrade your Model XM128 modem, turn the modem on and follow these steps:
1. Start any communications program that supports the X-modem Protocol.
2. Enter the command ATUPX.
Your Model XM128 modem responds:
You have chosen Xmodem (128 octets of data with checksum) protocol to
update your ISDN modem. Data in Flash ROM will be erased !!!
Are you sure (Y/N) ?
3. Press Y.
The following message appears:
Start programming, please upload.
4. Use the X-modem Protocol to upload the file ONETd.vvv to your Model XM128 modem.
This step updates the flash EEPROM of the modem with the new firmware. When
installation is complete, the Model XM128 modem restarts automatically.
Kernel Mode
In the unlikely event that your Model XM128 modem fails to respond to AT commands after
upgrading the EEPROM, turn on power to the modem. The reset prompts the modem to check the
integrity of the codes in the flash EEPROM. If proper valid firmware cannot be verified, the
modem initiates kernel mode. When the Model XM128 modem is in kernel mode, you can issue
limited AT commands. Start from step 2 of the upgrade instructions on this page.
