[HECnet] DU11 vs. DUV11

[John Wilson]

Trivia question:   what are the major differences between programming
the DU11 and the DUV11?   At least from the handbook descriptions, it
sounds like the DUV11's isochronous (= async?) mode works and the DU11's
doesn't, but that's the only difference I can see and I don't see how
it matters for DDCMP use.   And yet, DECnet/RSX has different names for
them, as if it's using separate drivers for each.
