This communication may not represent my employer's views, if any, on the matters discussed. Wasn't Phase IV the first release that supported Ethernet?
Yes.
My recollection is that DECnet always used DDCMP over serial lines. I thought the DMR did the DDCMP protocol in hardware.
Yes, yes.
Maybe DMZ's too?
No. This communication may not represent my employer's views, if any, on the matters discussed. On 07-Jun-13 18:24, Larry Baker wrote:

Seehttp://h71000.www7.hp.com/doc/spddecnetplusvax73.pdf page 13 table 2. DUP wasn't added in 7.3; it would have been there all along. This was just the first SPD I grabbed. There were also sync line adapters for Microvax - I have one here, I think. DSW4{1,2,3}. And QBus (DPV/DSV, BI (DMB/DSB). Gory details in the SPD. You needed the WAN Drivers layered product, though.The DUP11 is supported on a VAXBI system fitted with a DWBUA UNIBUS adapter for VAX 8200, VAX 8250, VAX 8300, VAX 8300, VAX 8350, VAX 8500, VAX 8530, VAX 8550, VAX 8700, and VAX 8800 systems only(Oddly, I didn't see DMC/DMR listed, but I do remember them working...)We ran DMRs between our VAX-11/780 and PDP-11/70 RSX-11M-Plus -- predating DECnet Phase IV. (Wasn't Phase IV the first release that supported Ethernet?) I remember doing poor-man's routing from the VAX through the 11/70 to an LSI-11/23 in a lab (over a DZ-11 async serial line!).My recollection is that DECnet always used DDCMP over serial lines. I thought the DMR did the DDCMP protocol in hardware. Maybe DMZ's too?Yes, Phase V supported DDCMP as a transport layer.
