Keywords: Negative information ?
Date: 14 Apr 92 19:29:34 GMT
Organization: Imperial College Computer Centre

Going through all the recent discussion on a new modem transfer protocol I
had several thoughts:

Could transfer be done in both directions ? Normally a file does only go
from a to b, and terminals usually transfer a lot more on the output side
than on the input side. But, for example, news transfers could send totally
unrelated information in both directions.

The protocol being discussed here seems to assume unlimited processing power
on both ends of the transmission. Could we harness that power in some other
way ? For example, if the receiving end could deduce what information to
expect, than it could use the back channel to transmit that, and the sending
end could subtract that information from what it sends, because the receiver
knows it already, thus reducing transfer time.

If the information was compressed before subtracting the back flow, it will
normally be effective to compress the difference again, which should yield
a line utilisation of up to 32 times the nominal capacity:
    original data compressed at 4:1
    lookahead subtraction at an assumed 2:1
    further compression at 4:1
I just wonder why nobody has thought of that before.

Nope.  v.32 = 9600bps
       v.32bis = (up to) 14400bps
       v.42bis = compression up to 4 times.

Thus v.32bis with v.42bis yields throughput up to 4*14400 or 57600bps.

From what one of Supra's distributors said last week, the v.32bis
model is still awaiting CSA approval.  Some Toronto dealers were
suggesting that they would have them in stock by the middle of April.
Most local retailers are now saying the end of April or beginning of
May.

  Using the keyword `preferences', I am assuming you are using an Amiga.  Not every term program requires that the Preferences Serial set-up be set to RTS/CTS.  NComm V2.0 does not (although earlier versions did).  This is an advantage to me because my PostScript setup supports only Xon/Xoff.

If the intent of the deal was to indeed prove that "loyalty pays", why
did there have to be an expiry date at all?

My own cynical self thinks that with the world of V.32bis modems
dropping in price like a stone, that Telebit ought to make it as easy as
possible to get into/stay with PEP.

These days, I'm able to get regular, everyday prices on V.32bis modems
for about the same price Telebit wanted for their special deal. It iused
to be that if you wanted a full Usenet feed, a Trailblazer was a must.
Now, V.32bis modems have dropped the entry price. What's Telebit's
answer? If they don't do something really soon, I see their share of
UUCP/Usenet sites sliding steadily, and possibly irreversably.

It's only a matter of time before the second-tier modem companies (like
Practical Peripherals or Cardinal) update their $275 V.32 modems to V.32bis.
Soon these modems will be commodity priced in such a way that the benefits of
PEP as we know it will simply not be worth the premium for many people.

I would say that it *is* in Telebit's interest to keep their current PEP
users -- as many as possible -- happy. A time limit on the offer is not
the best way to do it.

My personal belief is that "Loyalty Pays" was a marketing tactic/ploy to
see how many people would buy into the promise of a PEP upgrade, without
actually having it in their hands. It's a decent way for Telebit to bring
in cash before the product (3000 plus PEP) is complete.

   This is probably just a disagreement between the emulator and the

I am looking for information on fax data. How is the data transmitted?
The reason is simple. I have an old fax machine that I would like
to be able to use as a B&W scanner (It is a Sanyo, if this helps).
I want to be able to store the fax file as a picture file (Amiga iff
format preferred, but source code for IBM's or Mac's would be welcome).
I'll do the porting of the code, hack the hardware, and post the results
here as they become available.

I would like to share my voice line with a fax modem (my data line is already
dedicated to full time use).  I have an answering machine in my phone which
I also would like to continue to use, including the feature of answering on
2 rings if there are messages and 4 if there are none.  Thus the switch box
would have to work someting like:

	1) Initally the incomming line is switched to the phone
	2) The phone answers (on 2 or 4 rings), the switch only monitors
		the line, it does not answer the call.
	3) The switch box listens and if it detects a fax tone it
	4a) makes the phone see a hang up and switches the line to the fax
	4b) if no fax tone is detected the line remains switched to the phone.
	5) To get messages you use the touch tone keys, so the switch must
		ignore these (I assume the fax tone is distinct).

The hard part seems to be 4a, since the fax modem will not see any ringing but
just no-carrier/on-hook to carrier/off-hook (or whatever, you get the idea).
Will fax modems work this way?  Is there a switch box that works this way?
Better yet is there a fax modem with this functionality built in?  thanks.

The fax modem will be connected to my Quadra 700, A/UX system, but I'll deal
with that if I can solve the answering machine problems.

I am involved with an organization that has a substantial capacity

mail traffic to be forwarded out our FAX lines.  I would appreciate
any responses, discussion, etc. with regard to the following
questions:
 
1.  Do you think there is an interest in a capability to have
Internet Electronic Mail messages delivered by FAX to those without
an Email connection?

2.  Is there a service like this already accessible from the
internet?

3.  At what rate would you consider this capability a worthwhile
alternative to your current method of FAX?  [Compuserve charges
$0.75 for the first 1000 characters and $0.25 for each additional
1000 characters for transmission anywhere in the continental US]  
     
4.  What file formats (ASCII, PostScript, DVI, etc.) would you be
likely to use?

5.  If the rates were competitive, would your department/
organization/company consider this type of service as their
"network fax" solution?

6.  Do you think there would be interest in a broadcast (multiple
destination) FAX service from the internet?

7.  How many FAX's do you think you or your organization would send
per month through this type of service?

Any other comments on an Email to FAX service would be greatly
appreciated.

There are some real questions about the viability of Group 4, and a relatively
small number have been installed in the 8 years the standard has been in 
existence.  I am not sure why you would want to code it.  You might understand
a little better how it works by looking at the Red Book version, Rec's T.5, T.6,
T.62 and T.73.  The current Blue Book version is a procrustean fit into an ODA

The project was an experiment to gauge the demand for such a service.  It was privately funded, and the materials in the database were not "authorative".

The ITU computer department is well advanced on a e-mail based document database
and retrieval system.  I saw a demo last week in Geneva.

Questions still to be answered are who may have access and under what 
conditions, and the copyright problem.  I have no information on dates.

this is true, and it is the reasonable thing to do.  ultimately, you
probably don't need to have a fax where you already have a computer
network.

however, you can plunk a fax machine down almost anywhere there
happens to already be a phone connection (or even not, if you have a
cellphone nearby) and get faxes.  computer networks aren't this easy
