Run length encoding.

The number of consecutive "black" or "white" bits is stored, starting with a
white block. They are not stored as fixed length numbers (i.e. four bit for 
each group), but in variable length bit strings, with different bit strings
encoding black and white runs. Comes naturally to comms people, others
just need to use the look up table. To make it more interesting, the bit order
is inverted along the way, and documented in the opposite way to which it is 
used....

Gateway seems completely unable to make the internal V.32 modem
(made by TI) in the NOMAD 425DXL work with the WINFAX PRO
software that they bundle with the same machine.  I beleive that
the problem is in the modem hardware and Gateway's tech support 
after several hours spend trying to have me change just about every
parameter in the system finally admitted that they have a widespread problem
with this combination.

Gateway was unable to tell me if there is any package that is known to work
with this modem.  Until then, the modem works pretty well for
data, but cannot send or receive faxes at all.

Has anyone seen this modem work??  What configuration?

V.17 was balloted together with V.32bis, and both were adopted at 
the same time.  Yes, it is official.

TIA-592 (Class 2.0) has been approved at the committee level.  It 
has been submitted to the TIA executive committee for their approval 
(usually a formality), after which it will go to the American 
National Standards Institute Board of Standards Review (ANSI BSR) 
for their approval.  Only then will it be officially "adopted", but 
for all practical purposes you can consider it done now.

So far, Class 2.0 has not been implemented by any modem 
manufacturer.  Several manufacturers implement "Class 2" (the 
August, 1990 draft), but because of the ambiguities and 
incompleteness of that document, there are many differences between 
these devices.  We'll hope that many manufacturers rush to implement 
the real standard.

I just bought an April Technologies V.32bai / v.17 Data/Faxmodem.
It did not come with any fax software, so I tried bitfax and ql2fax.
Bitfax returns an error message "Not TR-29 software (COM1)".
Ql2fax returns "Modem not responding"

Any idea what kind of software this little beastie needs to play nice?

It's pretty obvious that April Tech is fronting for some other manufacturer.
Their name is only stickered on the box and screened on the modem.  
The modem manual makes no mention of them.  It simply reads "14,400 PocketFax/
DataModem".

Is there shareware software I could try?
Is there some comercial product that is good at talking to various types
of modems?

Isn't this standardized yet?

I'm sure this is a FAQ, but I have little knowledge or interest about the

"class 2" driver (whatever that means) only sends or receives faxes
about 50% of the time.  It always connects (either way) and then just
sits there in "pre-message" blinking the CD light idiotically until
it times out.  I know better than to try to ask Zoom and MTEZ has 
disappeared into WordPerfect.  So if anyone would like to explain this

Yeah, someone DID once.  Several other engineers and myself formed a
company which had such a box.  I cam up with the idea back in 1988
or so.  The company is virtually defunct now because of several
reasons, one of which was our inability to explain to a prospective
buyer how the concept works.  Either our ads had too little info, and
we were written of as yet-another-fax-switch, or are ads were too
wordy, and hence ignored.  Major sigh.

We have a patent for all the good it does us.

:device.

IMHO these devices are the best way to handle distribution to
multiple devices over a single phone line.  We use two of the
here to direct calls between different modem types (Everex 24/96D
fax modems and Telebit WorldBlazers) based on phone numbers.  We
used to also have separate modems for V.32/42..., but have
eliminated that requirement with the WBs.

This works quite nicely except that the comm software doesn't know
that these are really the same phone line on outgoing calls, but
since the switch disconnects all lines except the active one when
a line is in use, this isn't a real problem.

:So, does anyone sell an automatic A/B/C type device that will switch
:the call to different phone cables based on the distinctive ring?
:Should be a fairly simple electronic device to build, I would think.

We use Lynx RingDirector 4-line units.  The only problem I've had
was one with ground loops which I fixed by disconnecting all but
the center two wires on each phone cable.  Lynx customer service
was very helpful on that one.  The info I have on the company is:

Subject: Distinctive Ring -- A simple software implementation
Organization: University of Colorado, Boulder
Date: Wed, 16 Dec 1992 00:23:40 GMT

I tried a little experiment today.  I turned on my Courier 2400 baud modem
and ran Procomm on my IBM-PC and asked my wife at work to call each of
our distinctive ring numbers.  The results:

#	Type of Ring		Modem Output (via Procomm)
-	------------		--------------------------
A	LONG			RING
B	SHORT SHORT		RING RING
C	LONG SHORT LONG		RING

That is, when telephone number A was called (standard ring), the modem
printed "RING" for each ring; when telephone number B was called, the modem
printed "RING <newline> RING" for each ring; when telephone number C was
called, the modem printed "RING".

The modem was able to separate two consecutive shorts, but not a SHORT
followed by a LONG or a LONG followed by a SHORT.

Sooooo, it it would be straight-forward (< 100 lines of code) to write
a terminate-and-stay resident program that would turn on the modem Auto-answer
when a phone call comes in on telephone number B.  The algorithm would simply
time the interval of expected rings and count the number of rings within
the interval.  If the number of rings is 2, voila, turn on auto-answer.
Later, after the modem goes back onhook, it would turn it off.

This means that line B could be used as a dedicated modem number and even a
fax number, if you had one of those nifty fax/modems.  But since I don't
have one, I don't know exactly how the fax/modem board tells which part
should handle the incoming call (I suppose it could tell from the incoming
fax tone?).

Does this violate either of the two known distinctive ring patents
recently mentioned, or, is this a different technique?

The document describing group 4 compression is availible from CCITT, or

Try PMFAX from Sofnet for under OS2. I have it and Winfax pro and there 
is no comparison PMFAX blows it away.

Summary: Is there a new version working on Macintosh with System 7

My (pretty old) version of the Abaton Interfax Software works only with
System 6. When I try to use the control panel with System 7, I always get a
message saying "Interfax is shutting down".

Please write me, if anyone knows: Is there a new version of the software
working with System 7? Where can I get it (especially in Germany)?

Thanks if you write me your answer!
