If you are using Hyperterminal, click on Transfer/ Send File, select the file, specify 'XModem' as the protocol and
start the transfer with OK.

The firmware upload over a terminal program is only possible over a serial configuration interface.
TFTP
TFTP can be used to install new firmware on LANCOM. This can be done with the command (or target) writeflash. For
example, to install new firmware in a LANCOM with the IP address 10.0.0.1, enter the following command under Windows
2000 or Windows NT:
1
tftp -i 10.0.0.1 put Lc_16xxu.282 writeflash
Firmware upload via the serial interface with configuration reset
The serial interface can also be used to load firmware into the device. Entering the serial number instead of the
configuration password results in the device configuration being reset to its ex-factory settings. In this way you can
re-open the device in the case that the configuration password is lost and the reset button has been set to 'Ignore' or
'Boot only'.
1. Use the serial configuration cable to connect the device to a computer.
2. On the computer, start a terminal program such as Hyperterminal.
3. Open a connection with the settings 115200bps, 8n1, hardware handshake (RTS/CTS).
4. In the terminal program's welcome screen, press the Return key until the request to enter the password appears.
5. Enter the serial number that is displayed under the firmware version and press Return again.
1. The device now expects a firmware upload. To initiate this, in Hyperterminal you click on Transfer/ Send file and
select X-Modem as the transfer protocol.
5
Uploading the firmware in this way completely deletes the configuration, which is returned to its ex-factory
settings! Consequently, this option should only be used if the configuration password is no longer available.
