I'm a recent joiner to HECnet, and wondered if anyone else has played
around with Phase V software at all ?
Obviously HECnet itself is a Phase IV network, but you can connect Phase V
VAX endnodes using the Phase IV compatibility mode.
All my systems are simulated with simh, and getting an Ethernet connection
to work was very straightforward, there's just a bit more local
configuration required than with Phase IV.
However, I spent quite a few years at DEC working on VAX synchronous device
drivers, so I was interested to see whether I could get a WAN connection
going. The biggest issue was device support. DECnet-VAX Phase V doesn't
support any of the older microcoded interfaces (DMC11, DMV11, KMX11 etc),
and the later devices (DSV11, DSB32, DST32, etc) aren't supported by simh.
The only intersection is actually the DUP/DPV11, where there was a new VMS
driver (SEDRIVER) for Phase V, that replaces the
individual protocol-specific drivers that were previously used with these
devices.
I've spent quite a long time this week dredging stuff out of memory from 30
years ago, and still failing to get a DPV11 link to come up, until I
eventually realised that a) there are some significant differences between
the DUP and DPV, and b) simh does not support the DPV properly (how is one
supposed to know this?) ! So after changing my simulated microVAX into an
8600, and the DPV into a DUP, I've managed to get a DDCMP link to come up
between this and a PyDecnet router.
There still seem to be some rough edges, as it won't always come up until
PyDecnet is bounced, and it's also a bit slow for interactive use, as if
there's something that's only working on a retransmission, or timer expiry.
Anyway, it's been a fun nostalgia exercise to get this far, I'll probably
mess about with it some more. Let me know if you have any questions...
