I am trying to add more modems to an existing pppd termserver setup, on a
2.2.2 box with a 16-port Cyclom Y PCI card.  I am trying to add (and
migrate to) USR Sportster 336s.  Using the same software config that works
with the other modems (PPI V.34s), I get this error message from pppd:

Dec 15 15:43:06 sirius pppd[1895]: pppd 2.2.0 started by root, uid 0
Dec 15 15:43:06 sirius pppd[1895]: Connect: ppp0 <--> /dev/ttyc05
Dec 15 15:43:06 sirius pppd[1895]: Serial line is looped back.
Dec 15 15:43:06 sirius pppd[1895]: Connection terminated.

cu works fine.  The modem isn't set to any special loopback mode or
anything.  I have tried some different modem settings and nothing seems to
make a difference.  Anyone have any ideas?  Here is output form ATI4
(modem settings)
