(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.
