On old technology (300 baud lines or so) probably not, as many systems
would run out of serial ports.

But in general, if there is a pay as you use charge, with per-second and
per-byte charges for both lines and gateways there is a definite advantage 
in it. Thus it should be possible to use connection to a number of sites 
for telnet, ftp, nfs, what have you, ... transfers. 

With an ISDN setup the software would maintain those connections on the 
D-channel during idle time (say overnight) at high packet and no time 
charges, and build up and tear down connections as throughput requires it.

I don't really care if it is called multi-slip or parallel ppp (pppp) or
whatever, but is would definetly be useful, and by the time it is in place
a new set of acronyms will be in fashion anyway.

Maybe the natural place for this is the much vilified session layer, 
although I am sure the consolidation of multiple sessions was not 
envisioned for it when the seven layer model was formulated.

This may be ugly, but...

The Bit3 company makes a GIO to VME suite of products.  There are
plenty of VME Ethernet cards; in fact SGI sells some.  Given enough
time, you could have all the Ethernet controllers you could want.

The UNINET company makes a SCSI to GPIP & RS232 card.  They claim it
works very well.

My search has lead me to believe there are no useful Centronics to SCSI 
devices on the market.

My brother and I are developers.
We have just become proud owners of an Indigo  What a nice piece of hardware.
We have set out to develop some animation utilities.  We have started our
own file format for storeing and playing animations.  Its working well.
We are now at the stage that we want to develop some USER INTERFACES.

What should we use?  GL or Motif?  This will be using GL for the animation
playback but we have a number of problems.  GL does not have a widget library
AND, its possible in the future Sun may be able to do the type of stuff SGI can
and well if we do it in X, there would be much less development/port time
involved.

What do people think and what does SGI themself suggest.

Also keep in mind, we have not done any X/GL programming before.

A quick question for showcase experts ..

I want to create a text template, similar to the supplied "document" template and
then flow between the text objects where the objects are split over a number of
pages ... eg: page 1 has text block, page 2 has a graphic diagram (another template
type) and page 3 has another text object.  I would then like to flow text from page 1
to page 3.  If the template is created to try and automatically create a new page with
text object and then flow it grumbles because page 2 already has an object ... if you
create a text template without any flow characteristics and then, after applying that
template to page 1 and page 3, you try and flow between them showcase grumbles
about not being able to modify a template. Ummm ... seems like a simple thing to
do .... what is the solution.  I want to use a template as I can then apply a common
size of text object to the pages.

The backplane VME jumpers are between the upper connectors on the
upper row on the backplane.  There are the expected 4 jumpers as
you describe.  Slot one is the leftmost one, facing the machine
as you would when inserting a board.  I believe that the slots
are numbered, also.

Maybe.  If it is ISO 9660 or High Sierra format, probably.  If it

If you were thinking of NFS exporting it to the Suns, you can forget

I can't understand what you mean here when you say the "port mentioned
is an ESDI port". As far as I know, the twin tower only supported
SCSI cabling, not ESDI. You are trying to add a SCSI device, right?

What we did is buy the CHEAPEST reburbished SCSI device we could from
SGI that was housed in a twin-tower chassis. When we order it, it
was a QIC tape unit for about $1,000. We ripped out the tape unit
(attached to one of our Indigos) and placed a 1.2 MB Seagte in the
module. Since a new Archive Viper tape drive is about $550, you can
reason that we spent about $500 to buy a twin-tower module from SGI.
That's not much different that what they charge for a cable assembly
and you don't have to mess with buying an external chassis box.

On an IRIS 4D/440VGX, running 4.0.1, we noticed a peculiarity in SGI's
compilation systems.

Suppose two .o files are linked together.  One .o file provides routines
'main' and 'sub'.  The other provides 'func' and 'sub'.  Many UNIX linkers
will complain that 'sub' is multiply-defined and refuse to produce an 
'a.out'.  SGI's linker warns of the multiple definition, includes both
copies of 'sub' in the executable, and directs all references to the 
first 'sub' it encounters.  

We don't have the Compiler's Guide to determine if this "feature" is
discussed there.  Can anyone provide a rationale for this design decision
and implementation?

Adding peripherals to your twin tower is not really difficult, only
a little confusing at times.

There are three ways (well, maybe four) and they tend to be a cost/ease
related.  

Plan 1:
The easiest, and therefore the most costly is to buy a P4-XSCSI from
SGI and you will get an empty peripheral cannister that has a SCSI
connector on the back.  You can then daisy chain SCSI peripherals to
it.  This is easy.  The only thing the user has to do, assuming you
don't use SGI tech people, is to figure out how to 'un-terminate' the
top device on the peripheral tower.  This isn't hard... but, you do
have to figure out how to open the cannister.  It might be worth $200
for a field call to get  it done.  This thing used to cost $750.

Plan 2:
The next easiest is to get a HU-XSCSI.  This used to be $350 and was
a cable and a card that replaced the one in an existing cannister and
basically carried about the same level of expertise as plan 1 to
administer.

Plan 3:
Buy a cable kit from a reputable firm that replaces the internal
cannister cable.  Takes the same expertise as above and costs about
$200 if you buy one professionally or $30 if you make it yourself.
There is a somewhat higher level of expertise if you make it yourself
and you should really have a connector vice.  It may very well be worth
$200 if you want a professional looking backplate with cut-outs for
connectors.  If you do it yourself you will have a 3x3" hole in the
back.

Plan 1a:
Same as plan 1 but, use a recycled cannister from Falcon or a new one
from someone who makes them as a third party.

   Apparently, I don't have (I checked...) the /usr/include/cmplrs/stsupport.h

If you have the CD-ROM distribution of the OS, you do have the include
files.  They're in a package which isn't normally installed by default.  I
wish I knew the name of the package, but I don't.

Once you have those files installed, the rest of the installation should go

I need the highest possible bandwith between two workstations for the
purposes of file transfer between Cherry Hill, NJ to Antwerp, Belgium.
V32bis/V42bis modems and switched (dial) circuits look more attractive
than Ethernet Bridge,DSU/CSU, and leased 56Kbit/sec circuit from a cost
and complexity point of view. We need the bandwith only periodically.
But when the files are ready, we want as much bandwith as possible to
drive the transfer time down.

Could a sleazy trick like the following get us partway there until/if
slip can handle multiple serial lines? A) Configure both systems to 
look like gateways, i.e. two network addresses. B) split files to be
send into equal parts. C) rcp one part to REMOTEA and one to REMOTEB.
D) rsh a command to REMOTE to re-assemble the pieces.

>Would the effort to implement it be worthwhile?

It means a multi-million dollar per year contract to the end-user who
needs this capability to conduct its business.

>Would host-based compression in if_sl be more interesting?

Only if host-based compression substantially outperforms V42bis,
and/or is superior to compressing the files statically.

>Or PPP?

Should I be investigating this?

What about the limits on the serial port speed itself.  When V.FAST
modems become available will the current uart speeds (19.2K or 38.4K)
be too slow to allow for full throughput?
