2159.0. "VMS V5.3/DECW TCP/IP??" by HOTAIR::BOYLES (Albuquerque Onsite Presales Support) Mon Jan 29 1990 15:57

    I've got a question concerning the TCP/IP transport for VMS DECWindows.
    
    (1st correct me if I'm wrong)
    Now as I understand it... with VMS V5.3 you get DECWindows V2.0 which
    supports TCP/IP for the transport if you have the VMS/Ultrix Connection
    software (v1.2).  Now as I understand it you can use the TCP/IP
    transport without a Connection license, if you get the media kit.
    
    (My question)
    I also understand that the "hooks" are there for other TCP/IP vendors
    to utilize so that their products will also work with VMS/DECWindows.
      1.  Is this true?
      2.  If so... where are these "hooks" documented so that other TCP/IP
          vendors can "plug their product in"?
      3.  Do any of these 3rd party vendors currently have working versions
          with VMS/DECWindows?
    
    Any help would be appreciated.
    
    Regards,

Right about TCP support via UCX.  I don't know about the UCX license.

Regarding "hooks":  What we have done is to officially document the transport
interface to allow anyone to write a new transport image.  Other vendors can
use this documentation to write their own transport, including other TCP
vendors like Wollongang and Fusion.

Since they were the main reason we did the transport interface, I suppose you
could call it a hook.  On the other hand, we did not do anything specific to
other TCP vendors.

2159.2Some more TCP/IP answersSTAR::VATNEPeter Vatne, VMS DevelopmentMon Jan 29 1990 19:3021
Your understandings are correct... DECwindows in VMS V5.3 supports TCP/IP
with the VMS/Ultrix Connection, and you do not need a UCX license to use
it with DECwindows.  Therefore, customers need only order the media kit.
(They of course can't use the other UCX features like FTP or NFS unless
they do purchase a UCX license.)

To answer your questions:

1. Yes, there are hooks so that third party TCP/IP vendors can write
   their own transport interface.  Actually, anyone can write their own,
    provided they know BLISS, but I expect only the vendors will bother.

2.  The hooks are all documented in the new VMS DECwindows Transport
    Manual, available with VMS V5.3.   There is also an example transport
    in DECW$EXAMPLES:XPORT_EXAMPLE.B32 (plus a few other support files).

3.  Quite a few of the third party TCP/IP vendors for VMS were field
    test sites.  I don't know if they've announced availability yet.
    You probably should call them yourself if no one else has.

A word of caution:

If you don't have the UCX license, then you'll have a hard time starting the
application on the `other' machine in order to make use of the TCP/IP transport,
unless they both have DECnet or are part of a VAXcluster.

DECwindows does not specify any method for starting an application remotely.
Therefore, where TCP/IP is involved, the application is started in one of the
following ways:
	1. TELNET to client machine and run application
	2. rlogin to client machine and run application
	3. run application using rsh
	4. BATCH

I use the latter within a VAXcluster, and TCP/IP works fine.

    Thanks for the help  (.ALL).
    
    .3 makes a good point.

re: .2.2

Just out of curiosity, why do they have to know BLISS.

2159.6Why BLISS...STAR::VATNEPeter Vatne, VMS DevelopmentTue Jan 30 1990 22:3110
Implementors of transport interfaces should know BLISS, because that's the
language the example transport is written in.  I suppose one could write a
transport interface in another language, but since no one has ever tried a
language other than BLISS, I don't know if there are any major stumbling
blocks.  At a minimum, the transport interface has to be able to run in
exec mode, and be able to manipulate queues.

We didn't create examples in other languages because they would have been
expensive to produce, and all the major third-party TCP/IP vendors we asked
said that BLISS was okay with them.

From the V5.1 release notes for WIN/TCP for VMS (shipping this week)


New Features 

 o DECwindows Transport

   Support for the DECwindows transport
   has been included. This allows users to
   use DECwindows over the WIN/TCP
   product. Users must have VMS 5.3.


Information gathered from Mike Schwieterman,
                          The Wollongong Group
                          Tel (415)-962-7208


If you or your customers have a maintainence agreement for WIN/TCP, this
5.1 release is available by calling their Product Support Department at
(415)-962-7140.


According to Mike, Digital's interface to Wollongong is Bruce Alcock which ELF
points to at
