I've got a feeling that there's a need for some tweaking.

Quite a few times the modem would "CONNECT" but then pppd would say
that the modem had told it to hangup and terminated the call. It felt
like there was a race condition or two in timers.

I'm not sure if I'll persist with it for a whole lot longer - when I
did get it connected, the only O2 IP# that I could reach was the DNS
server and the DNS server was returning its own IP# for _every_ query
sent to it :-/

I don't know if further authentication is/was required, but this device
is just a hand-me-down to try out and has limited support...
