Hi, Is there a way to get the CBOS 2.4.3 for a 675 and install it with Linux via the terminal port and a com program. I have tried connecting via modem serial port but I'm not really sure how to do the upgrade. I'm in routing mode so I don't think I can use the tftp procedure as the router doesn't have a IP address. Any help appreciated, Eric :-) p.s. I hate to resort to another OS for this task.
