Two different variations of the Xmodem protocol are supported (CRC and
Checksum) for those serial communication packages that only support one or
the other. However, some programs can automatically adapt to the user’s
selection, making the specific Xmodem protocol selection arbitrary. The first
argument of the xmodem command indicates the mode, and must be set to
either “/crc” for Xmodem CRC mode, or “/cs” for Xmodem checksum mode.
As mentioned above, configuration files can be both downloaded and uploaded.
The second argument in the xmodem command indicates the action to take,
and must be set to either “/d” to download the configuration file from the unit, or
“/u” to upload a configuration file to the unit.
Figure 12 shows an example of initiating an Xmodem download in CRC mode.
Once the message “The interface is ready to send its configuration file via
Xmodem…Download the file now” appears, the user has 30 seconds to start
the Xmodem download. This can be performed in HyperTerminal by clicking
the “receive” button (
) on the tool bar. Figure 13 shows the dialog box that
will appear after clicking the “receive” button. Specify the folder in which to
place the received file, select Xmodem as the receiving protocol, and click
“Receive”. One last dialog box will prompt the user to name the received file,
and then the transfer will begin. This will only take several seconds to
complete, and at the conclusion the console will indicate the status of the
transfer and return to the entry menu.
