Correct if I'm wrong, but a PPP network stack means that you (also) have a
TCP/IP-stack? Then why not port the z88dk TCP/IP-stack? Before you get
vague ideas of a compiled C program, the stack is handwritten in assembly,
and has been optimized for ages. And it works. There is a link to the
TCP/IP-stack page on http://z88dk.sf.net/

But indeed you first need a working dailup. btw, you can connect an
external modem with a so called 'null-modem' to your graphlink. Speed of
your external modem doesn't matter, I've never seen a modem that doesn't
support 9600 baud.

I've read the Telnet83 (a VT100 client) docs and there's also stated that
such thing is impossible with the graphlink. But what about the
FastAVR-link? (see http://tilp.ticalc.org)
