3G modem problems
 
I am having trouble connecting a 3G modem.
The particular usb modem (BP3-EXT) is supplied in Australia through
Telstra, who refuse to support Linux.

There has been some excellent work on this problem (especially
http://quozl.linux.org.au/bp3-usb/) and people have reported successful
connections.
I have been able to follow this work to connect to the modem but there
seems to be some sort of block.

I quite new to Linux, ppp and modem connections and have pasted my
connection attempt below.
The connection seems to progress OK, until negotiations about
compression commence.

I would be extremely grateful for any advice on how to proceed.

Many thanks
Tony
