[comp.sys.mac.apps] DECwindows communications with a Mac

sellswor@jarthur.Claremont.EDU (Scott Ellsworth) (04/21/91)

  Hello all.

  So, does anyone know of a comm program for the mac that runs dec windows.

  It seems like there should be some good result from this DEC/Apple
cooperation, at least in my mind.

  One caveat; we will be talking to a VAX over a modem, not a nice, fast 
ethernet line.  Any suggestions?

  Please reply through e-mail to sellswor@jarthur.claremont.edu or
cwebb@vmsa.oac.uci.edu

  Thanks all.

  Scott

DEC and Apple have built PathWorks (sold by Dec, previously called LanWorks
but that name was already taken).  I am not a PathWorks user but I wouldn't
think that this would run over phone lines.  I think that it uses LAT, Dec's
proprietary ethernet protocol which will not run though a router.  So you
can't even use it over a software router between phone lines and ethernet.

DEC Windows (like X Windows) take up a TREMENDOUS bandwith.  This bandwidth
is enough to bring ethernet to it's knees.  I don't know if anyone in their
right mind would want megabytes of windowing info to be sent over modems.

So the answer is probably, No you can't because you wouldn't want to!

As always, just my thoughts...

In reading the MacX manual, it talks about MacX being used with something
called DEC LanWORKS for Macintosh to run DECwindows. I have no experience
with it, though.

I thought that eXodus, White Pine's X server product, had DEC connectivity  
stuff so you could run DECwindows.  Am I wrong?  Their # is 603-886-9050

Yes you are wrong.  DECwindows is a superset of Xwindows. 

In order to run DECwindows, you will need to run something that understands 
DECwindows.  I don't think that anything out there except DEC's own 
LanWORKS does this.

Actually, I am running DECwindows using eXodus, so this is eminently possible.

Nope.  eXodus runs them fine.  I've got both on my IIci, and have gotten
both to work quite nicely.  MacX is nice, cuz it's got rootless windows,
but I heard that eXodus is doing that too in the next release.

Quite right -- MacX runs DecWindows fine too -- it is "packaged" as part of
Pathworks, but is really an apple product.

First, I have to disappoint you a little.  There have been long conversations
on the subject of X over phone lines in comp.sys.mac.comm, and short of some
fairly incredible kludges, nothing has shaken loose.  The main barrier is lack
of SLIP or PPP support in MacTCP.  Is Apple listening?

But that's the only barrier.  DecWindows is X -- it uses its own upper layers,
look-and-feel, etc.

So, once you can get a SLIP link working, you should be home free with at least
two products.
