Among the features of _H_y_l_a_F_A_X are: +o _H_y_l_a_F_A_X runs as a network service; this means a modem may be effectively shared by a large number of users. +o _H_y_l_a_F_A_X can be configured to work with a wide variety of modems on a wide variety of systems. +o Access to the system can be restricted by the administrator to selected hosts and/or users. +o Transmission requests may be processed immediately (default) or queued for processing at a later time, in the manner of the _a_t(1) command. +o Remote facsimile machines may be polled to retrieve publicly available documents. +o POSTSCRIPT 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, _t_r_o_f_f(1) output, and Silicon Graphics images are automatically converted. Additional file formats can be added; see _t_y_p_e_r_u_l_e_s(4F). +o The _f_a_x_c_o_v_e_r(1) program can be automatically invoked to create a cover page for each facsimile, using information deduced by the _s_e_n_d_f_a_x command. Alternatively, users may supply their own cover pages using their preferred tools. +o 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 ----ssss option to all _H_y_l_a_F_A_X programs. Well known page sizes include: ISO A3, ISO A4, ISO A5, ISO A6, ISO B4, North American Letter, American Legal, American Page 1 (printed 6/24/99) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) UUUUNNNNIIIIXXXX SSSSyyyysssstttteeeemmmm VVVV ((((MMMMaaaayyyy 8888,,,, 1111999999996666)))) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) 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. +o Facsimile can be sent at low resolution (98 lines/inch) or medium resolution (196 lines/inch)-often called _f_i_n_e _m_o_d_e. Documents with mixed resolution pages are handled correctly. +o 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 resubmission. +o Support is provided for broadcasting facsimile. The _H_y_l_a_F_A_X server software optimizes preparation of broadcast documents and the client applications support the notion of a _j_o_b _g_r_o_u_p which permits a group of jobs to be manipulated together. +o 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 _H_y_l_a_F_A_X 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: +o _s_e_n_d_f_a_x, a program to submit outgoing facsimile; +o _s_e_n_d_p_a_g_e, a program to submit alpha-numeric messages to SNPP servers; +o _f_a_x_s_t_a_t, a program obtain status information about _H_y_l_a_F_A_X servers; +o _f_a_x_r_m, a program to remove jobs and documents; +o _f_a_x_a_l_t_e_r, a program to change parameters of queued jobs; and +o _f_a_x_2_p_s, a program that converts facsimile documents to Page 2 (printed 6/24/99) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) UUUUNNNNIIIIXXXX SSSSyyyysssstttteeeemmmm VVVV ((((MMMMaaaayyyy 8888,,,, 1111999999996666)))) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) 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 _H_y_l_a_F_A_X). Many systems also support submission of outgoing facsimile by electronic mail and/or graphical interfaces to the _s_e_n_d_f_a_x program. Such facilities are site-dependent; consult local documentation for more information. GGGGEEEETTTTTTTTIIIINNNNGGGG SSSSTTTTAAAARRRRTTTTEEEEDDDD To use the _H_y_l_a_F_A_X 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, /_u_s_r/_f_r_e_e_w_a_r_e/_b_i_n, the directory where the client application database files reside, /_u_s_r/_f_r_e_e_w_a_r_e/_l_i_b/_f_a_x, and the directory where document conversion programs reside, /_u_s_r/_f_r_e_e_w_a_r_e/_s_b_i_n (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 _c_s_h users, setenv FAXSERVER flake.asd or for _k_s_h or _s_h 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 _t_t_y_m_2 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 _s_e_n_d_p_a_g_e program; consult _s_e_n_d_p_a_g_e(1M) 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 ``_5_3_0 _U_s_e_r %_s _a_c_c_e_s_s _d_e_n_i_e_d.'' if access to your server is controlled and you are not properly Page 3 (printed 6/24/99) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) UUUUNNNNIIIIXXXX SSSSyyyysssstttteeeemmmm VVVV ((((MMMMaaaayyyy 8888,,,, 1111999999996666)))) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) registered or you may be prompted for a password and then denied service with ``_5_3_0 _L_o_g_i_n _i_n_c_o_r_r_e_c_t.''. DDDDIIIIAAAALLLL SSSSTTTTRRRRIIIINNNNGGGGSSSS A dial string specifies how to dial the telephone in order to reach a destination facsimile machine. _H_y_l_a_F_A_X 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 ``+_c_o_u_n_t_r_y-_c_o_d_e _l_o_c_a_l-_p_a_r_t''. CCCCOOOOVVVVEEEERRRR PPPPAAAAGGGGEEEESSSS The _s_e_n_d_f_a_x program can automatically generate a cover page for each outgoing facsimile. Such cover pages are actually created by the _f_a_x_c_o_v_e_r(1) program by using information that is deduced by _s_e_n_d_f_a_x and information that is supplied on the command line invocation of _s_e_n_d_f_a_x. Users may also request that _s_e_n_d_f_a_x not supply a cover page and then provide their own cover page as part of the data that is to be transmitted. Automatically-generated cover pages may include the following information: Page 4 (printed 6/24/99) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) UUUUNNNNIIIIXXXX SSSSyyyysssstttteeeemmmm VVVV ((((MMMMaaaayyyy 8888,,,, 1111999999996666)))) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) +o the sender's name, affiliation, geographic location, fax number, and voice telephone number; +o the recipient's name, affiliation, geographic location, fax number, and voice telephone number; +o text explaining what this fax is ``regarding''; +o text commentary; +o the local date and time that the job was submitted; +o the number of pages to be transmitted. Certain of this information is currently obtained from a user's personal facsimile database file; ~~~~////....ffffaaaaxxxxddddbbbb. Note that this file is deprecated; it is described here only because it is still supported for compatiblity with older versions of the software. The ....ffffaaaaxxxxddddbbbb file is an ASCII file with entries of the form _k_e_y_w_o_r_d :::: _v_a_l_u_e where _k_e_y_w_o_r_d includes: NNNNaaaammmmeeee a name associated with destination fax machine; CCCCoooommmmppppaaaannnnyyyy a company name; LLLLooooccccaaaattttiiiioooonnnn in-company locational information, e.g. a building#; FFFFAAAAXXXX----NNNNuuuummmmbbbbeeeerrrr phone number of fax machine; VVVVooooiiiicccceeee----NNNNuuuummmmbbbbeeeerrrr voice telephone number. Data is free format. Whitespace (blank, tab, newline) can be freely interspersed with tokens. If tokens include whitespace, they must be encloseed 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." Page 5 (printed 6/24/99) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) UUUUNNNNIIIIXXXX SSSSyyyysssstttteeeemmmm VVVV ((((MMMMaaaayyyy 8888,,,, 1111999999996666)))) HHHHYYYYLLLLAAAAFFFFAAAAXXXX((((1111)))) 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."

As a result it is being replaced by other, more straightforward databases that are managed by programs that front-end the _s_e_n_d_f_a_x program. CCCCOOOONNNNFFFFIIIIGGGGUUUURRRRAAAATTTTIIIIOOOONNNN FFFFIIIILLLLEEEESSSS _H_y_l_a_F_A_X client applications can be tailored on a per-user and per-site basis through configuration files.

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 ttttaaaagggg: _v_a_l_u_e where a _t_a_g identifies a parameter and a _v_a_l_u_e 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''.
