SENDFAX(1)SENDFAX(1)NAMEsendfax - submit a facsimile job for transmission
SYNOPSISsendfax [ options ] [ files... ]
DESCRIPTIONsendfax submits one or more facsimile transmission
requests to a HylaFAX facsimile server. Requests are nor
mally processed immediately, although they may also be
queued for transmission at a later time using a syntax
identical to the at(1) command. For each job that is
queued, sendfax prints a job identifier and a job group
identifier on the standard output. A job identifier is
the token by which jobs are identified within HylaFAX; job
group identifiers are used to reference a set of jobs that
have been submitted at the same time. Job and job group
identifiers can be supplied to the faxrm(1) command to
remove the jobs or to the faxalter(1) command to alter job
parameters.
Facsimile are made from the concatenation of a cover page
(see below) and one or more files specified on the command
line. If no files are supplied on the command line, send_
fax will read data from the standard input unless polling
is requested. Cover pages are distinguished for the pur
pose of generating ``continuation cover pages'' on the
server; these are makeup cover pages that are automati
cally generated if a job fails after sending the original
user-specified cover page.
sendfax passes POSTSCRIPT and TIFF documents directly
through to the fax server for transmission, and attempts
to convert other file formats to either POSTSCRIPT or
TIFF. In normal operation sendfax automatically converts
ASCII-text, troff(1) output, Portable Document Format
(PDF), and Silicon Graphics format images for transmis
sion. Support for other file formats can be easily added
through an extensible file typing and conversion facility;
see typerules(${MANNUM4_5}). Note that since TIFF Class F
documents are processed directly it is simple to forward a
received facsimile.
By default sendfax will generate a cover page for each
facsimile that is to be transmitted. This cover page is
created by the ancillary faxcover(1) program using infor
mation deduced by sendfax and by information supplied on
the command line. Automatic cover page generation may be
suppressed with the -n option.
In addition to sending documents, sendfax can be used to
poll a remote facsimile machine to retrieve waiting docu
ments. If the -p option is specified, a polling request
will be submitted to each destination. If a poll request
is made in conjunction with the transmission of documents,
the poll request will take place after the documents are
transmitted. Documents retrieved by polling are returned
to the requestor by electronic mail and may be viewed with
a suitable viewer program.
One or more destinations must be specified on the command
line using the -d option. A destination is the dialing
string to use to contact the remote fax machine. Phone
numbers may include non-alphanumeric characters for read
ability--only alphanumerics and ``+'' (for denoting a
country code) are significant in placing a call. Alpha
betic characters are automatically mapped to their numeric
key equivalents: ``abcABC'' to ``2'', ``defDEF'' to ``3'',
etc. Dialing prefixes, such as ``1'' and ``011'' (for
long distance calling in the United States) need not be
included if an unambigous number is specified. Examples
of unambiguous phone numbers are:
+31.77.594.131 to call the Netherlands
+14159657824 to call California
9657824 to make a local call
1-215-356-1666 to call Pennsylvania from within the US
Non-numeric strings, such as ``*70'' (to defeat call wait
ing), may be included in the destination phone number.
Whether or not they are stripped from the string used to
dial the destination fax machine is dependent on the dial
string rules configured for use on the server; c.f.
hylafax-config(${MANNUM4_5}) and dialrules(${MANNUM4_5}).
A destination may also be specified as user@fax-number.
In this case the user string will be passed to faxcover as
the identity of the recipient. Note that multi-word names
must be enclosed in quote marks; for example, ``Sam Lef
fler@+1.415.555.1212''.
The order of options on the command line is significant.
Each fax to be transmitted is assigned the current value
of parameters specified on the command line; e.g. whether
or not to generate a cover page. This means that options
that specify parameters for a particular destination must
precede the dialstring specified with the -d option. For
example,
sendfax-n -d 5551212 /etc/passwd
submits a fax to 5551212 that has no cover page while
sendfax-d 5551212 -n /etc/passwd
submits the same fax but with the default cover page han
dling. Note also that parameter values persist across -d
options so the following
sendfax-n -d 5551212 -d 5551313 /etc/network
submits two facsimile, both of which have no cover page.
OPTIONS-1 Transmit facsimile documents using 1-D MR com
pression. By default HylaFAX will use the
optimal compression scheme supported by the
transmitting modem and receiving facsimile
device.
-2 Transmit facsimile documents using 2-D MR com
pression, if possible. By default HylaFAX
will use the optimal compression scheme sup
ported by the transmitting modem and receiving
facsimile device.
-a time Schedule transmission up to one year in
advance at the indicated time. Time is speci
fied in the format: ``[HH:MM [AM|PM]|now] [+ N
period | month DD | dayofweek ] where month
can be Jan(uary), Feb(ruary), Mar(ch),
Apr(il), May, Jun(e), Jul(y), Aug(ust),
Sep(tember), Oct(ober), Nov(ember), or
Dec(ember); period can be minute(s), hour(s),
day(s), week(s), or month(s); dayofweek can be
Mon(day), Tue(sday), Wed(nesday), Thu(rsday),
Fri(day), Sat(urday), Sun(day); e.g. ``now +
30 minutes to schedule transmission 30 min
utes in the future. Trailing information in
the time field (such as YYYY) is ignored. By
default, sendfax schedules facsimile for imme
diate delivery. Time should be given in the
user's local time.
-b speed Transmit facsimile documents using a sig
nalling rate that is constrained to be at
least speed bits/second. If the specified
speed is greater than the transmitting modem
or receiver is capable of, it is reduced to
the highest possible speed both devices sup
port. If a negotiated signalling rate greater
than or equal to speed cannot be negotiated
then the job is aborted. Possible speeds are:
2400, 4800, 7200, 9600, 12000, and 14400. By
default HylaFAX will use the fastest possible
rate supported by the transmitting modem and
receiving facsimile device.
-B speed Try to transmit facsimile documents using the
desired signalling rate. Possible speeds are:
2400, 4800, 7200, 9600, 12000, and 14400. If
the specified speed is greater than the trans
mitting modem or receiver is capable of, it is
reduced to the highest possible speed both
devices support. By default HylaFAX will use
the fastest possible rate supported by the
transmitting modem and receiving facsimile
device (unless restricted by other server con
figuration); this option can be used to reduce
the speed. Note that international calls are
frequently more reliable when transmissions
are restricted to 9600 bits/second.
-c comments Pass comments to the faxcover(1) program for
inclusion in the comments field of any gener
ated cover page.
-C file Pass file to the faxcover(1) program for use
as the cover page template.
-D Enable notification by electronic mail when
the facsimile has been delivered. By default
HylaFAX will notify the submitter only if
there is a problem with a job.
-d destination
Create a job to transmit the supplied docu
ments to a facsimile machine at the indicated
destination. If the destination is of the
form ``user@phone-number'' then any cover page
will show user as the intended receipient.
-E Disable use of the Error Correction Mode (ECM)
when transmitting page data. By default
HylaFAX will attempt to use ECM when both the
trasmitting modem and receiving device support
it. Note that international calls are some
times faster when ECM is disabled. Beware
also that some modems and/or facsimile devices
do not properly implement ECM causing trans
mission failures.
-f from Use from as the identity of the facsimile
sender. Otherwise the sender is the user that
invoked sendfax. The sender is an account
name to which the HylaFAX software should
direct notification messages. The from iden
tity may be a fullblown ``From:'' line, e.g.
e.g. ``Joe Blow <joe@foo.com>'' and
``joe@foo.com (Joe Blow)'' are acceptable. If
no host-part is specified in the from string
the local hostname is used. This option is
useful when sendfax is invoked on behalf of
another user, such as in the implementation of
an electronic mail to fax gateway.
-F format Use the specified format when imaging tag
lines on outgoing pages. Consult the descrip
tion of the TagLineFormat parameter in
hylafax-config(${MANNUM4_5}) for an explana
tion of how to construct a format string.
Note that many locales require that proper
identification appear on all transmitted fac_
simile; when using this facility one should
always include proper identification (e.g. a
phone number) in the imaged taglines.
-h [modem@]host[:port]
Force the jobs to be processed on a specific
host and, optionally, using a particular
modem. The host may be either a symbolic name
or a network address. If no -h option is sup
plied, sendfax uses the FAXSERVER environment
variable to identify the HylaFAX server to
which the jobs should be directed. If no
server is specified then sendfax attempts to
contact a server on the local host. If no
modem is specified, the job will be submitted
to any available modem.
-i identifier
Use the identifier string in any notification
messages instead of the usual job identifier
number. This option is useful for applica
tions that cross reference notification mes
sages against job submissions.
-I time If a job must be requeued because of a commu
nication failure schedule the retry according
to the specified time. Times are given in
seconds. Minutes, hours, and days can be
specified with ``min'', ``hour'', and ``day''
suffixes, respectively. By default HylaFAX
reschedules jobs using retry times that depend
on the manner in which the job failed; this
interface permits a user to override this
algorithm and specify a single fixed retry
time for all communication failures.
-k time Kill the job if it does not complete in the
indicated time. The time is specifed using
notation identical to the -a option. Note
that the time is relative to the time of the
initial time-to-send. The default kill time
is ``now + 3 hours'' (three hours from the
time the job is first processed). To retry
for an hour, ``now +1 hour'' could be used.
-l Transmit the facsimile at a vertical resolu
tion of 98 lines/inch; otherwise known as low
resolution.
-m Transmit the facsimile at a vertical resolu
tion of 196 lines/inch; otherwise known as
medium resolution or fine mode.
-M mst Transmit facsimile documents using the speci
fied minimum scanline time. Possible times
are: 0ms, 5ms, 10ms2, 10ms, 20ms2, 20ms,
40ms2, and 40ms. If the specified time is
less than the transmitting modem or receiver
is capable of, it is increased to the lowest
possible time both devices support. By
default HylaFAX will use the lowest possible
time supported by the transmitting modem and
receiving facsimile device (unless restricted
by other server configuration). This option
is mostly useful for debugging.
-n Suppress the automatic generation of a cover
page for subsequent facsimile. Note that
polling requests do not receive a cover page
unless they are combined with the transmission
of one or more files.
-N Do not notify the sender by electronic mail
when the facsimile has been delivered or
requeued.
-p Poll each destination for any available docu
ments. If a poll request is made together
with document transmission, the poll operation
is done after the documents are transmitted.
Documents received by polling are returned to
the sender by electronic mail.
-P priority Assign the specified scheduling priority to
subsequent jobs. A priority is an integer
value in the range [0-255]. Lower values
result in higher priority processing. By
default, each job is assigned 127 for an ini
tial scheduling priority. If a job's priority
is greater than bulk faxes then the job's pri
ority is raised (numerically lowered) for each
failed attempt to transmit so that retransmit
attempts are done ahead of newly submitted
jobs. In the case of bulk faxes (numerically
higher than 190), then the job's priority is
lowered (numerically raised) for each failed
attempt to transmit so that the whole of the
bulk-queued jobs will be attempted before any
are retried. The priority may also be speci
fied as one of the following symbolic names:
default or normal (127), bulk or junk (191),
high (63).
-R Enable notification by electronic mail when
the facsimile has been delivered and when it
is requeued for retransmission. By default
HylaFAX will notify the submitter only if
there is a problem with a job.
-r regarding
Pass regarding to the faxcover(1) program as
the value of the ``Re:'' field of any gener
ated cover page.
-s size Set the page size to use for the transmitted
facsimile. Facsimile are normally imaged with
a system-default page size (usually letter-
size pages, 8.5" by 11", for sites in North
America). Alternate page sizes are specified
symbolically using either the name or abbrevi
ation of an entry in the pagesizes(${MAN
NUM4_5}) database; e.g. a3 (ISO A3), a4 (ISO
A4), a5 (ISO A5), a6 (ISO A6), b4 (ISO B4),
na-let (North American Letter), us-leg (Ameri
can Legal), us-led (American Ledger), us-exe
(American Executive), jp-let (Japanese Let
ter), and jp-leg (Japanese Legal). Compar
isons are case-insensitive and any match of a
substring of the full page-size name is suffi
cient; e.g. ``legal'' would match ``American
Legal''.
Note that it may not be permissible to image
into the full page area; the guaranteed repro
ducible area for a page is typically inset.
Also, note that while arbitrary page sizes can
be specified through the page size database,
only a limited set of page dimensions are sup
ported by the Group 3 facsimile protocol.
Thus if an odd-size facsimile is submitted for
transmission it may not be possible to deter
mine if it can be sent until the fax server
establishes communication with the remote fac
simile machine.
-t tries Make no more than tries attempts to send the
facsimile. By default, HylaFAX will terminate
a job if: 3 consecutive attempts to send a
particular page fail, or it appears the
receiver is not a facsimile machine. Other
wise HylaFAX places no limit on the number of
attempts to send a facsimile, instead termi
nating a job if it is not completed within a
kill time timeout interval. Note that a try
is a call in which carrier is established and
the facsimile protocol is commenced; this is
contrasted with a call attempt that might have
failed because the line was busy.
-T maxdials Make no more than maxdials calls in attempting
to send the facsimile. By default, HylaFAX
will redial 12 times before killing a job.
-U voice-no Pass voice-no to the faxcover(1) program as
the sender's voice number.
-V voice-no Pass voice-no to the faxcover(1) program as
the destination person's voice number.
-w Wait for the job to complete before ending the
sendfax session. If this option is used, the
sendfax process will not terminate until the
job is completed.
-W fax-no Pass fax-no to the faxcover(1) program as the
sender's fax number.
-x company Pass company to the faxcover(1) program as the
destination company name.
-X company Pass company to the faxcover(1) program as the
sender's company name.
-y location Pass location to the faxcover(1) program as
the destination company's location.
-Y location Pass location to the faxcover(1) program as
the sender's company location.
-v Print information on the standard output about
each conversion and cover sheet generation
operation it does. If -v is specified twice,
the protocol between sendfax and the hfaxd
server process that does the submission work
on the remote machine is also displayed.

DIAGNOSTICS
The following messages are generated because of problems
encountered on the local machine.
Could not call server. The facsimile server on the remote
machine did not respond.
No input data; tranmission aborted. No data was supplied
(typically on the standard input). No facsimile will be
sent.
Error converting data; command was %s." A data conver
sion operation failed; the shell command that was used is
printed.
Can not convert %s. Data needed to be converted for
transmission, but the required conversion rule was not
located. This may indicate that the HylaFAX software was
incorrectly installed; or perhaps that an NFS-mounted
directory is temporarily unavailable.
%s: Can not determine file type. sendfax was unable to
deduce the type of the file.
%s: Not a regular file. The file is something other than
a regular file; for example, a directory.
The following messages may be printed by sendfax. These
messages describe problems encountered by the server pro
cess on the remote machine. This list is incomplete;
other messages may be generated by the server under
unusual circumstances.
