Hmm.  That looks a lot raw MNP or V.42.  That's not surprising at all.
Your modem is somehow misconfigured -- the "CONNECT 28800/V34/NONE"
message indicates that the modem is negotiating into so-called
"buffered" mode (V.14) operation.  This isn't good.  It means that
normal V.42 error control and V.42bis compression are both disabled.
The fact that you're getting MNP or V.42 frames means that the the
peer modem *IS* trying to use V.42 or MNP.  That's just not going to
connect to PPP at all.

You either need to add the magic "AT" commands to your chat script to
enable normal negotiation or otherwise permanently configure the modem
to work right.

1. pppd and Windows DUN

I have a Linux 2.0.27 box acting as a PPP server for a group of Windows 95
machines using dial up networking.  I am using agetty on the Linux box to
start the pppd when the modems connect.   The two machines can not agree on
a set of link configuration parameters.  The Windows machine appears to be
NAKing the LCP packets that are sent from the Linux machine.  After a number
attempts the Windows DUN pops a dialog that indicates that a configuration
could not be agreed upon.  Any insight into how to get this playing would be
