Q.    Frequently Asked Questions
===============================================================================

Q.1    Can I use my * data modem to send/receive faxes?
-------------------------------------------------------------------------------

In a word, no.  Unless your data modem has specific additional support for fax,
you cannot communicate with fax devices using a data (only) modem.

Simply put, the problem is that the modulation methods (tones) used to
communicate data are different from those used to communicate faxes.

Typically the modulation schemes used for fax are synchronous half-duplex
while those used for data (at least by most UNIX and PC people) are
asynchronous and full-duplex.

Also, data modems, once they have negotiated a modulation scheme, tend to
continue with the same one through out the session.  Fax modems switch
before and after each page between a high-speed modulation scheme used
to transmit the image data and a lower (300 or 2400 bps) scheme to exchange
control information.

The following table outlines this briefly  (see also part 1 of this FAQ
for definitions of V.*).

  Data Rate                   Data Modulation Std.       Fax Modulation Std.
  ========================+==========================+========================
   9,600 bps              |            V.32          |       V.29
  ------------------------+--------------------------+------------------------
  14,400 bps              |            V.32bis       |       V.17
  ========================+==========================+========================


-------------------------------------------------------------------------------
Q.1A    Can my fax modem transmit data?
-------------------------------------------------------------------------------

In a word, maybe.  There is a standard proposed by the EIA/TIA/ANSI called
Binary File Transfer (BFT) that extends the fax Group III modulation and
protocols for bulk data transfer.

The problem, of course, is that few fax modems or software packages provide
support for this mechanism.


-------------------------------------------------------------------------------
Q.2    How can I fax PostScript or PCL documents using computer-based fax?
-------------------------------------------------------------------------------

In addition to the basic software to drive your fax modem/board, you will need
specific software that can convert PostScript or PCL files into a raster image
format compatible with your fax software package.

GhostScript, for example, is a publically available software package that
can convert PostScript into raster image format (although there are varying
opinions on the quality of the font support).

In the commercial world, most of the vendors of fax software provide software
that can handle PostScript and/or PCL.

When purchasing such software (a) check how many different fonts are supported
(it's a pain to be able to use, say, NewCentury on your laser printer only to
find it is not included in your fax package), and (b) in the case of PCL, check
which level of the language is supported (PCL-4 does not support scalable
fonts, PCL-5 does).


-------------------------------------------------------------------------------
Q.3    How can I view incoming faxes on my computer?
-------------------------------------------------------------------------------

In the PD world, there are a number of image-viewing packages available for
X (such as xv).

In the commercial world, most fax vendors provide support for the commonly
available devices (in the case of UNIX, X; in the case of PC-UNIX, VGA
and HGA support. Some vendors support other graphics-capable terminals such as
the Wyse WY-160.)


-------------------------------------------------------------------------------
Q.4    How can I print incoming faxes on my computer?
-------------------------------------------------------------------------------

Most fax software packages include software to convert fax images into print
data streams compatible with dot matrix, HP PCL, or PostScript printers.

Also the publically available (where?) pbmplus filter kit will handle most
image formats.


-------------------------------------------------------------------------------
Q.5    Can fax modems also handle data or voice calls?
-------------------------------------------------------------------------------

Not all fax boards can handle data (some are fax only).  Most (all?)
external fax modems can handle data as well as fax.

Some (but not all) fax modems and software can automatically distinguish
between data and fax calls and answer them appropriately

Some DOS/WINDOWS based products can automatically distinguish between voice and
fax/data calls and operate as a digital answer machine as well as a fax machine.

Also, several companies sell devices which can switch incoming calls between a
fax machine, a telephone answering machine, and a modem.

[Suggestions anyone?]


-------------------------------------------------------------------------------
Q.6    What resolution are fax images?
-------------------------------------------------------------------------------

The standard resolution for faxes is 3.85 scan lines/mm (approx. 98 dpi
vertically) with 1728 pixels across a standard scan line of 215 mm (approx.
204 dpi horizontally).

The optional "fine" resolution is 7.7 scan lines/mm (approx. 196 dpi
vertically) with the same horizontal resolution.

Many Group III fax machines use non-standard frames to negotiate higher
resolutions (typically 300x300 dpi and 400x400 dpi) with other fax machines
by the same manufacturer.

Two fax machines (or modems) must negotiate a common resolution, page width,
and page length before sending each page.  The standard requires that all
Group III fax machines suppport at least standard resolution and A4 size
so that common ground can always be found.

Extensions to the Group III standard to support these higher resolutions
in a standard way have been proposed.  Their current status is not known
<Need more information>.

<Need more information on resolutions supported by Group IV>.


-------------------------------------------------------------------------------
Q.7    Can I take a fax file and edit it?
-------------------------------------------------------------------------------

When faxes exchange information, it is done in the form of compressed images
(with the exception of BFT).  If you wish to edit or otherwise manipulate a
received fax file you have two options:

 1 - edit the file using a "paint" program that will accept the fax file
     (unfortunately there is a wide range of file formats for image files
     and you may have to work to find a format that is common between your
     fax application and your paint program).

 2 - pass the file through an OCR program that will attempt to convert the
     image into ASCII (or word processing file format).  The problem here is
     that most OCR programs are tuned to work with 300x300dpi images and faxes
     are either 98x204 or 196x204.


-------------------------------------------------------------------------------
Q.8    Is there a standard program interface (API) for fax communications?
-------------------------------------------------------------------------------

There are many API's that are used for fax communications. Words marked by
-word- are further explained in the glossary in Part 1 of this FAQ.

At the hardware level, the two standards that govern the exchange of commands
between a host computer and a fax modem are EIA-578 (-Class 1-) and EIA-592
(-Class 2-).

At the software level there is one "official" standard and a number of
"industry standards".  The one "official" standard is ITU-T T.611
(<need more information on this standard>).

The most widely known industry standards are -CAS- (Communicating Applications
Standard (?)) invented by Intel and DCA and tied closely to the Intel
architecture, and -FaxBios- (developed by an industry consortium) which is less
machine-dependent (implementations for MS-DOS and WINDOWS have been published
and sporadic work on UNIX and other bindings is underway).


-------------------------------------------------------------------------------
Q.9    How can I share my single phone line with voice, fax, data, etc.
-------------------------------------------------------------------------------

There are a number of devices on the market (suggestions from happy campers
welcome) that will try to distinguish between an incoming voice, fax, or
data call and route the call appropriately.

These fax switches attach to the phone line and then the other devices (your
normal voice phone/answering machine, fax machine, data modem, etc.) are
attached to the fax switch).

All devices work on one of two general principles: listening for CNG or voice,
or listening for distinctive ring patterns (cadences).

In the first case the device will answer the phone and try to guess what it
should do based on what it hears.  Some machines play back a sound of a
phone ringing so that humans dialling in think the phone is still ringing
when in fact the fax switch is listening to see if the call is from a fax
machine or a human.  If the CNG tone (see Part 1 for a definition of CNG)
from the calling fax machine is heard, then the switch connects the call to
the fax machine, otherwise the call is deemed to be a voice call and is
connected to your phone/answering machine.

A slightly more sophisticated approach is for the fax switch to answer the
phone and play a short recorded announcement.  If, during the announcement
the CNG tone is heard, then the call is switched to the fax machine. If no
CNG tone is heard but sound is heard after the announcement, then the call
is assumed to be voice and switched appropriately.  If nothing is heard then
the switch either considers the call a data call and switches it to a modem
or considers it a fax call from a machine that does not generate a CNG and
switches it to the fax machine.

The other approach relies upon an optional service available from some telcos
called "SmartRing", "Distinctive Ring", "RingMaster", "Ident-a-Ring", etc.
This feature allows one to have more than one phone number associated with
the same phone line.  Incoming calls using the different phone numbers can be
differentiated by the different ringing patterns (i.e. one long ring, two short
rings, three short rings, etc.)  The fax switch distributes the call based on
the ring cadence it detects.

The advantage of the first approach is that one does not have to send more
money to the phone company (or depend upon the availability of the "SmartRing"
feature being available).  The disadvantage is that it is not always reliable
(especially in the face of fax machines that do not generate CNG tones).

The advantage of the second approach is that it is very very reliable. The
disadvantage is that it requires the availability of the "SmartRing"
feature from one's telco as well as sending more money to the telco every
month.

FlexFAX
=======

    Overview
    --------
    FlexFAX is a facsimile system for UNIX systems.  It supports:

    o sending facsimile
    o receiving facsimile
    o polled retrieval of facsimile

    Facsimile can be any size (e.g. A4, B4), either 98 or 196 lpi, and
    transmitted/received as either 1D-encoded or 2D-encoded facsimile data
    (2D-encoded data is frequently more compact and hence takes a shorter
    time to communicate).

    Outgoing documents can be any format; the sendfax program uses a
    rule-based definition file similar to the System V /etc/magic file
    to deduce document types and to decide how to convert each document
    to a form suitable for transmission (either PostScript or TIFF/F).
    Automatic cover page generation is supported and users can easily
    tailor cover pages to their environment.  A simple text-based
    phonebook database is supported by sendfax.  Information is also
    provided on how to trivially setup an email to fax gateway service.

    Incoming facsimile are stored in a receiving area as TIFF/F files and
    may be automatically delivered by mail and/or printed.  A fax server
    status program, faxstat, can be used to monitor the send and receive
    queues, as well as the state of facsimile servers.

    The system supports a wide variety of fax modems.  Any Class 1 or
    Class 2 modem should work with the system.  The following modems have
    been used successfully with the software:

    Class 1 modems:
        Digicom Scout+        (firmware revision 2A19/2931 or newer)
        Nuvo Voyager 96424PFX    (firmware revision AF-C2500-E0)
        SupraFAX v.32bis    (firmware revision V1.200-H or newer)

    NOTE: SEE THE SECTION "Class 1 Modem Support" FOR IMPORTANT INFO ON THE
          CLASS 1 MODEM SUPPORT

    Class 2 modems:
        Boca M1440E        (firmware revision V1.270 or newer)
        Dallas Fax <something>    (no longer sold, not recommended)
        Everex 24/96D        (no longer sold)
        Hayes Optima 24+Fax96   (firmware revision TR00-J260-001 XXX or newer)
        Multi-Tech 1432BAI    (firmware revision 0307 I or newer)
        SupraFAX v.32bis    (firmware revision V1.200-C or newer)
        Telebit WorldBlazer    (firmware revision LA7.01)
        Twincom 144/DF        (firmware revision V1.200 or newer)
        ZyXel U1496E        (firmware revision 5.01 or newer)

    Other modems:
        Abaton InterFax 24/96    (no longer sold)

    Note however that some modems perform better than others.  The file
    MODEMS included in the distribution provides information about each
    modem that has been tried.

    sco        SCO ODT 2.0 (incomplete)

    Systems that are marked (incomplete) compile properly and can be used
    to send and receive facsimile, but may have known problems or may be
    lacking some utilities such as the faxaddmodem installation script.

    Porting the software is usually straightforward provided there is a
    working C++ compiler (e.g. gcc), PostScript imaging facility (e.g.
    ghostscript), and support for a limited subset of the POSIX system call
    interface.  System requirements are described more fully in the source
    code distribution.


    How to Obtain the Distribution by FTP
    -------------------------------------
    The source code is available for public ftp on
    sgi.com            sgi/fax/v2.1.src.tar.Z
        (192.48.153.1)

    You can also obtain inst'able images for Silicon Graphics machines from
    sgi.com            sgi/fax/v2.1.inst.tar
        (192.48.153.1)

    For example,
    % ftp -n sgi.com
    ....
    ftp> user anonymous
    Password: <use mail address as password>
    ftp> cd sgi/fax
    ftp> binary
    ftp> get v2.1.src.tar.Z
    ....
    ftp> quit

    In general, the latest version of the 2.1 release of the software is
    always available as "v2.1.src.tar.Z" or "v2.1.inst.tar" in the ftp
    directory.  This file is a link to the appropriate released version (so
    don't waste your time retrieving the linked file as well!) Any files of
    the form v2.1.*.patch are shell scripts that can be used to patch older
    versions of the source code.  For example, the file v2.1.0.patch would
    contain patches to update v2.1.0.tar.Z.  Patch files only work to go
    between consecutive versions, so if you are multiple versions behind
    the latest release, you will need to apply each patch file between your
    current version and the latest.


GNU NetFax (a.k.a. fax-3.2.1)
=============================

on uunet.uu.net as systems/gnu/fax-3.2.1.tar.z (gzip format)
    To answer all the queries on NetFax:

    - I have taken over maintenance of NetFax.
    - I am currently integrating numerous fixes provided by various
      people which include:
        - support for Zykel Modems
        - Use more standard Class 2 commands
        - Setup configuration files for modems
        - support for Xenix
          (This isn't a priority, except that I'm already doing it
           for a client)
        - Better compilation and installation
    - There are a lot of problems with the current release, I don't
      expect that it will work on the majority of modem/system combinations
      without work.
    - If you have any fixes, or improvements please send them to
      me [e-mail] or [e-mail]
    - I hope to have a new release out in a few weeks.

    Following are some hints on getting the current version of
    NetFax working (for the impatient :)  I haven't tried all of these
    but they may help.

    - Use GNU make
    - It won't work on Xenix
    - If when you send a fax, it gets received twice as long as it
      should (22 inches instead of 11) try:
        - Use dfaxlow driver with Ghostscript (easiest) or
        - Change the source to use the +FDCC=xxxx/+FDCS=xxxx instead of
          +FDT=xxx

    The following modems are reported to work with NetFax 3.2.1

    Supra FaxModem 14.4 (v. 1.20C or later)
    Vivi 2496ef FaxModem (Has the resolution problem described above)
    Everex 24/96 D

    If you'd like to help me testing the new version, especially if you
    have something other than Supra Faxmodems, drop me a line.
