Here at BBN, we actually returned a LH/DH-11 to ACC on the belief that it was broken--this was a new machine supporting an 1822 Arpanet interface and running Ultrix 1.1 (1.1 being needed because of DMZ-32 hardware on this machine.) Naturally, we foolishly didn't suspect the software--I mean, DEC doesn't even officially support the non-DEC peripherals, so one wouldn't expect the IMP software to change. Ultrix 1.0 (sans DECnet) works fine. Turns out that the changes needed for DECnet did indeed "break" 1822 support (and maybe other devices--I haven't tried anything but DEUNA and 1822)--TCP/IP over the DEUNA works fine. We spoke to Ultrix engineering, and volunteered to help them fix this problem, since we knew that if we wanted our machines up and running quickly, this would be the only way to ensure that, since DEC does not have an Arpanet-style connection to any of its engineering VAXes. We have both running now, under a quick-and-dirty fix, and should have a DECnet-compatible fix which can be tested at DEC in a few more days. I can't comment on when it will be available from DEC. I might mention that DEC has been extremely responsive to this problem-- we've had the pleasure to speak with people who really know their stuff. I think their Ultrix software support system and the communication between support and engineering has improved by several orders of magnitude from our earlier experiences of a year ago, to the extent that I am quite happy to recommend their support service. -- /Steve Dyer {harvard,seismo}!bbnccv!bbncc5!sdyer sdyer@bbncc5.ARPA
