87.0. "ASYNC DECnet on KAV30" by TRN01::SICUREZZA () Wed May 12 1993 15:02

    Hi,
    a question to CROSBIE referring his answers on note 64 regarding DDCMP
    async support on KAV30,
    
    what about DDCMP implementation on async ports?
    I'm looking to connect as DECnet a PC to KAV30 avoiding ETHERNET
    cable using async port on PC (supported) and serial port on KAV30.
    
    Any chances?
    
     Thanks in advance,    MARINO FORMIA    DS-TURIN

    Again, this is not really a KAV30 specific question, you may get a
    better response from the VAXELN notesfile.  However, VAXELN only supports
    DECnet over ethernet.  

    DDCMP is supported as a datalink level protocol.  For a full
    DECnet (Phase IV) implementation, you also need routing, NSP, and
    session layers.  In VAXELN these DECnet layers are implemented as
    part of the ethernet drivers.  DECnet under VAXELN provides Phase IV
    end-node support only (i.e. no routing).  To support Asynchronous
    DECnet on a serial port it would be neccessary to implement
    DECnet routing support for VAXELN as DDCMP is only a point to
    point protocol.

    A more cost effective solution might be to buy an ethernet card
    for the PC.
