27.5 Example 1K Xmodem Firmware Upload Using
HyperTerminal
The ZyAIR supports the uploading of firmware files using TFTP (Trivial File Transfer Protocol) over LAN.
Although TFTP should work over WAN as well, it is not recommended.
To use TFTP, your computer must have both telnet and TFTP clients. To transfer the firmware and the
configuration file, follow the procedure shown next. This procedure is a HyperTerminal example. The
procedure for other serial communications programs should be similar.
Use telnet from your computer to connect to the ZyAIR and log in. Because TFTP does not have any
security checks, the ZyAIR records the IP address of the telnet client and accepts TFTP requests only from
this address.
Follow these steps to upload a new firmware file from your computer to the ZyAIR.
Step 1.
Enter HyperTerminal and type [ESC] to go to the status screen. This will reboot the ZyAIR.
Step 2.
When the HyperTerminal screen shows EDORAM Testing, enter X to go to a console mode.
Step 3.
Type DLS and press [ENTER].
