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!).</div>

<div>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?</div>
