D-2 Upgrading Software
Upgrading Through a PC
Upgraded routing software can be installed by connecting a computer to your router through a
LAN connection.
To install the software through a LAN connection, you need a computer equipped with the
following:
An Ethernet LAN interface card and packet driver software for that card loaded at software
interrupt 0x66
The following software:
CLAMPROG.EXE used to upgrade the router
ISDNPROG.EXE used to upgrade the TA code
PKUNZIP.EXE used for software updates supplied in a compressed format
Example: CLAMPROG.EXE CLAMR.BIN -i63 would program the router through a packet driver
loaded at interrupt 0x63.
To install the software, follow these steps:
1. Load the packet driver at the appropriate interrupt on your PC.
Depending on the driver you have, you might need to be running in DOS mode rather than
Windows.
2. If your router is connected to a hub, disconnect it and connect it directly to the PC so that
the PC and router are isolated from the rest of your LAN.
Only one router at a time can be updated by using this procedure.
3. Type DEFCON to connect to the built-in interface of the router and clear the
configuration.
Allow the router to reboot.
Note: CLAMPROG.EXE and ISDNPROG.EXE expect the packet driver to be loaded at
interrupt 0x66 by default, but this default can be overridden by the [-i<INT>] optional
parameter on the command line.
