Its even worse, if you upload a config file, same size as the rom-0 file, 
but filled with total crap the modem reboots (it does thatautomaticlty 
after uploading a new image) and after that the modem is broken. You ONLY 
have the ability to upload a new image via a serial port then, and most 
customers just have to bring back their unit. The modem is waiting after 
upload of a broken image, with a x-modem session. And there it ends. Even 
if you upload the previous image it wont work. Nice stuff :(

There are two files you can toy around with in this case, ras and rom-o
ras is the image file, rom-0 is 'just' the config. 

Bye,
Raymond.
