        After my earlier miscounting I'd better check
        carefully :-0 but if this is labelled B1 (and
        there is another one labelled B2 on *some*
        MicroVAX 3100 Model 20s) and it is three
        rows of pins ... then it is a synchronous
        communications connector. The same
        connector was used on several other
        synch comms options (DEMSA, DECnis,
        DSV11, DSB32, DMB32 and DSF32).
        The interface presented (X.21, V.35,
        RS422, RS423) was determined by the
        stub cable you plugged in.
