    We run a static asynch DECnet link over an LT-0-xx circuit under
    VMS 5.0-1 with little trouble. It isn't fast, and DEC won't
    support it, but it works! We run it out from a 6210, through a
    DEBNA, a DECserver 200, a CASE mux network, into a DHV11 on a 750
    (VMS 4.7), at 4800 baud. 

    If you're getting "No such device" or similar errors from NCP,
    make sure you have loaded NODRIVER in SYSGEN, and defined the
    LTA terminal in LATCP (LTLOAD).
