       HylaFAX is a telecommunication system for UNIX® systems.  Among the
       features of HylaFAX are:

       •  HylaFAX runs as a network service; this means a modem may be
          effectively shared by a large number of users.

       •  HylaFAX can be configured to work with a wide variety of modems on a
          wide variety of systems.

       •  Access to the system can be restricted by the administrator to
          selected hosts and/or users.

       •  Transmission requests may be processed immediately (default) or
          queued for processing at a later time, in the manner of the at(1)

       •  Remote facsimile machines may be polled to retrieve publicly
          available documents.

       •  POSTSCRIPT®, PDF, and TIFF Class F documents are passed directly to
          the fax server for transmission; the system attempts to convert
          other file formats to either POSTSCRIPT or TIFF through the use of
          an extensible file typing and conversion facility.  In normal
          operation ASCII-text, troff(1) output, and Silicon Graphics images
          are automatically converted.  Additional file formats can be added;
          see typerules(5F).

       •  The faxcover(1) program can be automatically invoked to create a
          cover page for each facsimile, using information deduced by the
          sendfax command.  Alternatively, users may supply their own cover
          pages using their preferred tools.

       •  Facsimile are normally imaged in a system-default page size (usually
          letter-size pages, 8.5" by 11", for sites in North America).
          Alternate page sizes can be specified with a -s option to all
          HylaFAX programs.  Well known page sizes include: ISO A3, ISO A4,
          ISO A5, ISO A6, ISO B4, North American Letter, American Legal,
          American Ledger, American Executive, Japanese Letter, and Japanese
          Legal.  Note that it may not be permissible to image into the full
          page area; the guaranteed reproducible area for a page is typically
          smaller.  Also, note that while arbitrary page sizes can be
          specified, only a limited number of page dimensions are supported by
          the facsimile protocol.  Thus if an odd-size facsimile is submitted
          for transmission it may not be possible to determine if it can be
          sent until the fax server establishes communication with the remote
          facsimile machine.

       •  Facsimile can be sent at low resolution (98 lines/inch) or medium
          resolution (196 lines/inch)—often called fine mode.  Documents with
          mixed resolution pages are handled correctly.

       •  Users are notified by electronic mail if a job can not be
          transmitted.  It is also possible to receive notification by mail
          when a job has been completed successfully and each time that the
          job is requeued for retransmission.  Any untransmitted documents are
          returned to the sender by electronic mail in a form suitable for

       •  Support is provided for broadcasting facsimile.  The HylaFAX server
          software optimizes preparation of broadcast documents and the client
          applications support the notion of a job group which permits a group
          of jobs to be manipulated together.

       •  Support is provided for transmitting alpha-numeric messages to pager
          devices or GSM mobiles using the Simple Network Paging Protocol
          (SNPP) and the IXO or UCP protocol (for message delivery).

       The HylaFAX software is divided into two packages: software used on
       client machines and software used on machines where one or more modems
       reside.  Client software includes:

       •  sendfax, a program to submit outgoing facsimile;

       •  sendpage, a program to submit alpha-numeric messages to SNPP

       •  faxstat, a program obtain status information about HylaFAX servers;

       •  faxrm, a program to remove jobs and documents;

       •  faxalter, a program to change parameters of queued jobs; and

       •  fax2ps, a program that converts facsimile documents to POSTSCRIPT so
          that they may be viewed with a POSTSCRIPT previewer or printed on a
          POSTSCRIPT printer (this program is actually part of the companion
          TIFF distribution that is used by HylaFAX).

       Many systems also support submission of outgoing facsimile by
       electronic mail and/or graphical interfaces to the sendfax program.
       Such facilities are site-dependent; consult local documentation for
       more information.

       To use the HylaFAX client software on your machine you need to either
       load the appropriate software on your machine, or you need to locate a
       machine that already has the client software installed and setup
       symbolic links to the appropriate directories.  If you choose the
       latter, then beware that you need links to three directories: the
       directory where client applications reside, /usr/bin, the directory
       where the client application database files reside, /usr/lib/fax, and
       the directory where document conversion programs reside, /usr/lib/fax
       (the last two directories may be the same on your system).

       Once the software is setup on your machine you need to locate a host
       that has a facsimile server that you can use.  The host, and possibly
       the modem on the host, should be defined in your environment in the
       FAXSERVER variable.  For example, for csh users,

              setenv FAXSERVER flake.asd

       or for ksh or sh users,

              FAXSERVER=flake.asd; export FAXSERVER

       If there are multiple modems on your server then you may be assigned to
       use a specific modem.  For example, if you are to use the modem
       attached to the ttym2 port on the server machine, then the FAXSERVER
       variable should be setup as

              FAXSERVER=ttym2@flake.asd; export FAXSERVER

       (Note: the SNPPSERVER environment variable is used instead of FAXSERVER
       by the sendpage program;  consult sendpage(8C) for more information.)

       Note also, that before you can submit outgoing facsimile jobs the
       administrator for the facsimile server may need to register your
       identity in an access control list.  You will encounter the message
       ``530 User %s access denied.''  if access to your server is controlled
       and you are not properly registered or you may be prompted for a
       password and then denied service with ``530 Login incorrect.''.

       A dial string specifies how to dial the telephone in order to reach a
       destination facsimile machine.  HylaFAX permits arbitrary strings to be
       passed to the facsimile server so that users can specify credit card
       information, PBX routing information, etc.  Alphabetic characters are
       automatically mapped to their numeric key equivalents (e.g.
       ``1800GotMilk'' becomes ``18004686455'').  Other characters can be
       included for readability; anything that must be stripped will be
       removed by the server before the dialing string is passed to the fax
       modem.  Private information such as credit card access codes are
       withheld from status messages and publicly accessible log files (with
       proper configuration).  Facsimile servers also automatically insert any
       leading dialing prefixing strings that are required to place outgoing
       phone calls; e.g. dialing ``9'' to get an outside line.  Additionally,
       if a phone number is fully specified with the international direct
       dialing digits (IDDD), then any prefixing long distance or
       international dialing codes that are required to place the call will be
       inserted in the dial string by the server.  For example,
       ``+31.77.594.131'' is a phone number in the Netherlands; it would be
       converted to ``0113177594131'' if the call is placed in the United
       States.  The number ``+14159657824'' is a phone number in California;
       if this number is called from within the 415 area code in the United
       States, then the server would automatically convert this to ``9657824''
       because in the San Francisco Bay Area, local phone calls must not
       include the area code and long distance prefixing code.

       The general rule in crafting dial strings is to specify exactly what
       you would dial on your telephone; and, in addition, the actual phone
       number can be specified in a location-independent manner by using the
       IDD syntax of ``+country-code local-part''.

       The sendfax program can automatically generate a cover page for each
       outgoing facsimile.  Such cover pages are actually created by the
       faxcover(1) program by using information that is deduced by sendfax and
       information that is supplied on the command line invocation of sendfax.
       Users may also request that sendfax not supply a cover page and then
       provide their own cover page as part of the data that is to be

       Automatically-generated cover pages may include the following

       •  the sender's name, affiliation, geographic location, fax number, and
          voice telephone number;

       •  the recipient's name, affiliation, geographic location, fax number,
          and voice telephone number;

       •  text explaining what this fax is ``regarding'';

       •  text commentary;

       •  the local date and time that the job was submitted;

       •  the number of pages to be transmitted.

       Certain of this information is currently obtained from a user's
       personal facsimile database file; ~/.faxdb.  Note that this file is
       deprecated; it is described here only because it is still supported for
       compatibility with older versions of the software.

       The .faxdb file is an ASCII file with entries of the form

              keyword : value

       where keyword includes:

              Name          a name associated with destination fax machine;

              Company       a company name;

              Location      in-company locational information, e.g. a

              FAX-Number    phone number of fax machine;

              Voice-Number  voice telephone number.

       Data is free format.  Whitespace (blank, tab, newline) can be freely
       interspersed with tokens.  If tokens include whitespace, they must be
       enclosed in quote marks (``"'').  The ``#'' character introduces a
       comment—everything to the end of the line is discarded.

       Entries are collected into aggregate records by enclosing them in
       ``[]''.  Records can be nested to create a hierarchy that that supports
       the inheritance of information—unspecified information is inherited
       from parent aggregate records.

       For example, a sample file might be:
              [   Company:   "Silicon Graphics, Inc."
                  Location:  "Mountain View, California"
                  [ Name: "Sam Leffler"     FAX-Number: +1.415.965.7824 ]

       which could be extended to include another person at Silicon Graphics
       with the following:
              [   Company:   "Silicon Graphics, Inc."
                  Location:  "Mountain View, California"
                  [ Name: "Sam Leffler"     FAX-Number: +1.415.965.7824 ]
                  [ Name: "Paul Haeberli"   FAX-Number: +1.415.965.7824 ]

       Experience indicates that the hierarchical nature of this database
       format makes it difficult to maintain with automated mechanisms.  As a
       result it is being replaced by other, more straightforward databases
       that are managed by programs that front-end the sendfax program.

       HylaFAX client applications can be tailored on a per-user and per-site
       basis through configuration files.  Per-site controls are placed in the
       file /usr/lib/fax/hyla.conf, while per-user controls go in ~/.hylarc.
       In addition a few programs that have many parameters that are specific
       to their operation support an additional configuration file; these
       files are identified in their manual pages.

       Configuration files have a simple format and are entirely ASCII.  A
       configuration parameter is of the form
            tag: value
       where a tag identifies a parameter and a value is either a string,
       number, or boolean value.  Comments are introduced by the ``#''
       character and extend to the end of the line.  String values start at
       the first non-blank character after the ``:'' and continue to the first
       non-whitespace character or, if whitespace is to be included, may be
       enclosed in quote marks (``"'').  String values enclosed in quote marks
       may also use the standard C programming conventions for specifying
       escape codes; e.g. ``\n'' for a newline character and ``\xxx'' for an
       octal value.  Numeric values are specified according to the C
       programming conventions (leading ``0x'' for hex, leading ``0'' for
       octal, otherwise decimal).  Boolean values are case insensitive.  For a
       true value, either ``Yes'' or ``On'' should be used.  For a false
       value, use ``No'' or ``Off''.

       Incoming facsimile are received by facsimile servers and deposited in a
       receive queue directory on the server machine.  Depending on the
       server's configuration, files in this directory may or may not be
       readable by normal users.  The faxstat program can be used to view the
       contents of the receive queue directory:

       Received facsimile are stored as TIFF Class F files.  These files are
       bilevel images that are encoded using the CCITT T.4 or CCITT T.6
       encoding algorithms.  The fax2ps(1) program can be used to view and
       print these files.  A file can be viewed by converting it to POSTSCRIPT
       and then viewing it with a suitable POSTSCRIPT previewing program, such
       as xpsview(1) (Adobe's Display POSTSCRIPT-based viewer), ghostview(1)
       (a public domain previewer), or image viewer programs such as
       viewfax(1) (public domain), faxview(1) (another public domain TIFF
       viewer program), xv(1) (shareware and/or public domain), or xtiff(1) (a
       program included in the public domain TIFF software distribution).
       Consult your local resources to figure out what tools are available for
       viewing and printing received facsimile.

       HylaFAX client applications communicate with servers using either a
       special-purpose communications protocol that is modeled after the
       Internet File Transfer Protocol (FTP) or, when submitting alpha-numeric
       pages, the Simple Network Paging Protocol (SNPP), specified in RFC
       1861.  All client programs support a -v option that can be used to
       observe the protocol message exchanges.  In some situations it may be
       more effective to communicate directly with a HylaFAX server using the
       client-server protocol.  This can be accomplished with an FTP or Telnet
       client application; though an FTP client is recommended because it
       implements the protocol needed to obtain server status information.
       For information on the server-side support provided with HylaFAX
       consult hfaxd(8C).  For documentation on the client-server fax protocol
       consult RFC XXXX (to be filled in).

       This section gives several examples of command line usage; consult the
       manual pages for the individual commands for information on the options
       and program operation.

       Doe at the number (123)456-7890 using fine mode; the server will
