I am rapidly losing whatever hair I have left trying to get a dmr-11
point-to-point TCP/IP link set up between two VAX 750's running across
town.  The basic problem is that even after what looks like a successful
invocation of ifconfig, "netstat -i" reveals no packets being sent.
BTW, one host is running 4.3 beta, the other Ultrix 1.2 beta.

Briefly, the sequence I'm using is:

/etc/ifconfig dmc0 inet myaddr destaddr

A subsequent 
/etc/ifconfig dmc0
reveals
dmc0: myaddr --> destaddr netmask ff000000 flags=51<UP,POINTOPOINT,RUNNING>

"Netstat -r" demonstrates that a route has been entered of the form:

Routing tables
Destination     Gateway         Flags    Refcnt Use        Interface
destaddr        myaddr          UH       0      33         dmc0
localnetname    myaddr-ether    U        4      932        de0
loopback-net    localhost       U        1      9          lo0

However, a "telnet destaddr" (or any other operation which would
cause IP packets to be sent to destaddr) does not produce any
packets sent through the dmr, at least if "netstat -i" is to
be believed.  Straight zeroes all the way across.

Am I forgetting something?  Thanks for any clues you might provide.
