Well, I've pinned down the problem, but I still don't know what's
happening ! Here's my log:

Ok, I'm sending my first LCP.

That's the *real* data.

This actually says: "User Process PPP. Written by Toshiharu OHNO.\r\n"
-direct now switches off this rubbish.

This actually says: "Using interface: tun0\r\n", followed by the LCP data
I wrote to the modem in the first place.

Strangely enough !
I've added a NAK for the "same magic" error, as per the rfc and I've
removed all of the startup printf's in -direct mode. I'll keep
trying to corner this.
