Subject: mpd -- configuration for "server" side?

I've got Archie's multi-link ppp "mpd" running on two boxes: one at my
house with 2.2.5-STABLE, the other at my ISP with 2.2.1-RELEASE.  I
want the home box to mpd-dial the ISP-box's mpd and stripe two POTS
lines.

I've been able to config the home box to dial out a single channel
into a couple people's terminal servers -- Ascend, Livingston. I'm
only trying to use one modem initially.  It acts like normal kernel
mode pppd with approximately the same performance.


What I can't figure out is how to get the ISP mpd to listen for
connections and answer the phone. Am I being lame? The normal mpd.conf
setup seems oriented for dialing out, but I've got the link set to
"answer-ring" thinking that would cause the daemon to camp on the
line, and have also turned off "bw-manage" thinking that this would
cause it to dial-on-demand rather than camp. I've tried various
permutations with no luck.

Or is mpd supposed to be spawned by init from /etc/ttys? Tried that
too and got the expected "respawning to fast" from init; perhaps I
invoked it wrong. 

I've searched the archives and haven't found anything besides "where
can I find it" messages. I would have posted to -questions but most
the traffic on this was on -hackers and -isp.

Heres my ISP-side mpd configuration info; what's wrong with this
picture? Any pointers would be most welcome. Thanks.
