You want to do the following:

(1) Use the MultiNet Network Configuration Utility (MULTINET CONFIG) to enable
    the MultiNet VMS/ULTRIX Connection (UCX) $QIO interface:

    $ MULTINET CONFIGURE
    NET-CONFIG>SET LOAD-UCX-DRIVER TRUE

    You'll need to reboot your system after issuing this command to get it to
    take effect.  Using the UCX $QIO emulation, MultiNet makes DECwindows
    "think" that it's talking to UCX.  (also means that we can support other
    applications written to run over UCX without recompilation or relinking!)
    See "Configuring MultiNet Services" in the MultiNet System Administrators'
    Guide for more detailed information about MultiNet DECwindows support.

(2) Make sure the VMS DECwindows client has access to the HDS server (using
    whatever security mechanisms HDS provides).

(3) Do a:

    SET DISPLAY /CREATE /TRANSPORT=TCPIP /NODE=hostspec

    where "hostspec" can be either an IP address or a host name.  Running
    your application now should cause the user interface to pop up on your
    HDS system.  If it doesn't, please call TGV MultiNet tech support at
    (408) 427-4366 or send email to service@tgv.com to pursue the matter
    further.

WIN/TCP uses their own DECwindows transport mechanism (hence the different
transport name).  Don't know why they only work with an IP address and not a
host name.

Since we support the UCX $QIO interface, we use standard
DECW$TRANSPORT_TCPIP.EXE provided by DEC.
