XMODEM Text Configuration File
You can set the repeater IP address during the boot process by downloading a
text configuration file using the XMODEM protocol. This requires a PC with a
serial port, a text editor (to change the IP address), an XMODEM file transfer
program, and a null modem cable. You can substitute a pair of modems with
modem cables for the null modem cable if you want to set the IP address
remotely.
The text configuration file is used in conjunction with a second binary Flash
image file to update the Flash in the repeater (see the section "XMODEM
Implementation" in this chapter). The text file uses acronyms to simplify the
firmware parsing. The following example configuration file updates the
repeater configuration parameters and prepares the repeater for a firmware
download (i.e., erases the current Flash). This example assumes that the COM
serial port is used for a SLIP connection. If not, the serial IP address and
NetMask should be set to "0.0.0.0".
