Data in Flash ROM will be erased !!! Are you sure (Y/N) ? 3. Press Y. The following message then appears: Start programming, please upload. 4. Use the Xmodem protocol to upload the file ONETd.vvv to your TA. This step updates the TA's flash EEPROM with the new firmware. When installation is complete, the TA will restart automatically. Kernel Mode In the unlikely event that your TA fails to respond to AT commands after upgrading the EEPROM follow the procedure below: 1. Power on the TA128. The reset will prompt the TA128 to check the integrity of the codes in the flash EEPROM. 2. If proper valid firmware can not be verified, the TA128 will initiate Kernel Mode. Once it is in Kernel mode, you can issue limited "AT" commands. From this point, you can start from item 3 of our upgrading procedure. 95

2.
Start any communications program that supports the Xmodem
protocol, and type:
ATUPX<Enter>
TA128 responds:
You have chosen Xmodem (128 octets of data with
checksum) protocol to update your TA. Data in
Flash ROM will be erased !!!
Are you sure (Y/N) ?
3.
Press Y. The following message then appears:
Start programming, please upload.
4.
Use the Xmodem protocol to upload the file ONETd.vvv to
your TA. This step updates the TA’s flash EEPROM with the
new firmware. When installation is complete, the TA will restart
automatically.
Kernel Mode
In the unlikely event that your TA fails to respond to AT
commands after upgrading the EEPROM follow the procedure
below:
1.
Power on the TA128. The reset will prompt the TA128 to check
the integrity of the codes in the flash EEPROM.
2.
If proper valid firmware can not be verified, the TA128 will
initiate Kernel Mode. Once it is in Kernel mode, you can issue
limited “AT” commands. From this point, you can start from
item 3 of our upgrading procedure.
