Howdy,

I am hoping that someone has run upon this problem and knows how to
fix it. I am trying to establish a PPP connection between a SUN/IPX at
work and my NeXT at home.  The connection goes through a Xyplex
terminal server.  

When I start the connection, it seems that LCP negotiation completes.
Then, I get stuck during the NCP negotiation.  It seems that the
machine at work sends many configuration requests.  My machine at home
receives them (and ACK's each option, there are no NAK's) finally
returning a CONFACK.  However, the machine at work never receives this
acknowledgement.  After a short period, the machine at work will send
another configuration request and the whole thing starts over again.

After a while, I kill PPP on my home machine.  The LCP terminate
message is received and handled properly by the machine at work.

I tried forcing an asyncmap of all 1's (as Karl Fox suggested), but
that didn't seem to help my problem.  The problem may be that my
connection is not passing all control characters properly, but I don't
know how to verify this (suggestions here also appreciated).

BTW, I am running on a Supra v.32bis modem at 2400 with MNP5
compression on an 040 cube using hardware flow control. I don't
know what type of modem is on the other side.

Any help would be sincerely appreciated.

Below is a copy of the debug output for a run.  The machine at work is
"anat1" and my home machine is "sidney".

I'll summarize if anyone is interested.
