Hi:

I've been trying to connect a PC running netbsd with PPP to a NetBlazer with
PPP built-in and turned on.

The modems are very similar -- both are TrailBlazer modems.  They don't
seem to have any problems communicating without PPP (I am composing this
over the modems).

I have seen this physical NetBlazer unit communicate via modems with  a
far-flung remove PPP site.  The PPP in use at that far site was a version
provided by Morningstar on the Sun Sparc2.

I *USED* to be able to get thru the LCP negotiation okay with this netbsd
kernel and the NetBlazer in question.  About two weeks ago, it stopped
working.  As best I can tell, nobody reconfigured the NetBlazer and I
didn't (knowingly) change the configuration of the machine here.

I have tried a number of options from the pppd man page in the options
file for PPP.  I have turned on the debugging capabilities for kernel
and pppd debug.  I can easily capture the LCP negotiation.  Specifically,
it seems each side is ignoring the other.  The remote side is sending my
side a 24 byte packet.  My side then sends out some bytes.  A 28 byte
packet is received followed by  another 24 byte packet and we start the
whole sequence over again.

A couple of items:  1) does anybody have an inkling of what's going on
inside this connection?  2) does anybody have a spec for the content
of the bytes sent back and forth during LCP negotiation?

Any other suggestions?

Your help is appreciated.
