Does anyone run TCP/IP link from VMS/Eunice/Wollongong 785 over 56kb line
without using DEC's DMR11 card? In particular is there an interface
available that handles more than one line or at least doesn't draw 12 amps
to handle one line? We must do packet forwarding so we can't use a "TCP/IP
in a card" solution.

At my end will be an 11/780 SVR2 UNIX system running Wollongong TCP/IP. The other end may be a BSD system or possibly another SVR2. I would very much like to know what options exist: hardware and their drivers. art gross ihnp4!mhuxm!agg

Well, if TWG is still using BSD drivers like they have before, you can also use a DMC board, since the BSD code uses the DMR in DMC mode. You don't get sources with their stuff though, so you cant look at the driver and tell, but give 'em a call and see. Be glad you dont use a DEUNA, that sucker takes 15 AMPS and 2 UNIBUS slots. (Handy for cooking lunch though) Also, I hope the put in the hacks to allow the TCP/IP routing to handle point to point links properly. 4.2 didn't until UCB got a link to the UCSF Med. Center using DMC-11's. 4.3 handles that fine though, but I doubt TWG has a copy of that yet. All the TWG code is derived from the UCB stuff, so I'd expect similar problems with it. This is especially true if both ends of the pipe are gateways to local nets and you need to pass routing info bewteen them. Of course, if you cant get it to work or cant afford the DMC power reqts, if you have a couple of 11/23's lying around you could add ether and serial sync. boards to them (they're Qbus so its generally cheaper than UNIBUS) and turn them into dedicated gateways. That way you can chuck the Vaxen and binary only software entirely, and you'll get better performance to boot (Vaxen under general purpose OS's dont make for fast gateways).
