SENDPAGE(1)		    General Commands Manual		   SENDPAGE(1)

NAME
       sendpage	- submit a pager job for transmission

SYNOPSIS
       sendpage	[ options ] [ message...  ]

DESCRIPTION
       sendpage	 submits  a  pager  transmission request to a server using the
       Simple Network Paging Protocol (SNPP) described in RFC 1861.  Pager re-
       quests  specified with sendpage are normally processed immediately, al-
       though 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,
       sendpage	prints a job identifier	on the standard	output.	 A job identi-
       fier  is	 the  token  by	which jobs are identified within HylaFAX.  Job
       identifiers can be supplied to the faxrm(1) command to remove the  jobs
       or to the faxalter(1) command to	alter job parameters.

       Pages  may be sent to one or more destination paging terminals and, op-
       tionally, include a text	message	(depending on the  capability  of  the
       receiving device).  Each	destination is identified by a Pager Identifi-
       cation Number (PIN) specified with the -p option; for example, sendpage
       -p  12345  ``Help, the fax machine is on	fire!''.  A PIN	is typically a
       numeric string though it	may also be an alpha-numeric  alias  depending
       on the capabilities of the SNPP server.

       Text  messages can be specified on the command line or taken from stan-
       dard input.  The	-n option must be used if no text  message  is	to  be
       supplied	with the page request--as for a	numeric-only pager.  Text sup-
       plied to	the paging system is sent exactly as submitted	including  any
       newline,	 carriage  return, or non-ASCII	data.  Message preparation in-
       cluding filtering and formatting	must be	done prior to  submitting  the
       data to sendpage.  Note that text supplied on the command line does not
       include a trailing newline character.

       The order of options on the command line	is significant.	 Each page  to
       be transmitted is assigned the current value of parameters specified on
       the command line; e.g. whether or not to	queue the request.  This means
       that  options that specify parameters for a particular destination must
       precede the pager ID specified with the -p option.  For example,

	      sendpage -l 2 -p sam Your	network	is hosed

       submits a page to ``sam'' that has service level	2 while

	      sendpage -p sam -l 2 Your	network	is hosed

       submits the same	page but with the default  service  level  (1).	  Note
       also that parameter values persist across -p options so the following

	      sendpage -l 0 -p sam -p 5551212 Your network is hosed

       submits two pages, both of which	have service level 0.

OPTIONS
       -a time	   Schedule  transmission  at  the  indicated time.  Times are
		   specified using the syntax of the at(1) command; e.g. ``now
		   +  30  minutes'' to schedule	transmission 30	minutes	in the
		   future.  By default,	sendpage schedules pages for  ``now''.
		   (In	SNPP  parlance this option specifies the ``hold	time''
		   for the page; and may result	in the page being delivered to
		   the paging terminal but not delivered to the	user until the
		   specified time.)

       -D	   Enable notification by electronic mail when	the  page  has
		   been	 delivered  to	the  service provider.	This option is
		   meaningful only when	communicating with a HylaFAX server.

       -f from	   Use from as the identity of the message sender.   Otherwise
		   the	sender	is the user that invoked sendpage.  The	sender
		   is an account name to which the HylaFAX software should di-
		   rect	email notification messages.  The from identity	may be
		   a  fullblown	 ``From:''  line,  e.g.	   e.g.	  ``Joe	  Blow
		   <joe@foo.com>''  and	``joe@foo.com (Joe Blow)'' are accept-
		   able.  If no	host-part is specified in the from string  the
		   local  hostname  is used.  This option is useful when send-
		   page	is invoked on behalf of	another	user, such as  in  the
		   implementation of an	electronic mail	to pager gateway.

       -h [modem@]host[:port]
		   Force  the jobs to be processed on a	specific host and, op-
		   tionally, using a particular	modem.	The host may be	either
		   a  symbolic	name or	a network address.  If no -h option is
		   supplied, sendpage uses the SNPPSERVER environment variable
		   to  identify	 the  SNPP server to which the pages should be
		   directed.  If no server is specified	then sendpage attempts
		   to  contact	a  server  on  the local host.	If no modem is
		   specified, the job will be submitted	to any	available  mo-
		   dem.

       -I time	   If  a job must be requeued because of a communication fail-
		   ure 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 al-
		   gorithm and specify a single	fixed retry time for all  com-
		   munication  failures.   This	option is meaningful only when
		   communicating with a	HylaFAX	server.

       -l level	   Specify a particular	service	level to use in	 delivering  a
		   page.   A  service level defines both a scheduling priority
		   and the time	that a client is willing to wait to  find  out
		   if  delivery	 is successful or not.	Normal delivery	is ob-
		   tained with level  1	 (default).   The  SNPP	 specification
		   identifies  level  0	 as the	highest	priority service level
		   with	 levels	 1-7  lower  priority  and  levels  8-11  ven-
		   dor/server-specific.	  For HylaFAX server machines the map-
		   ping	between	service	level and scheduling priority  is  de-
		   fined  by the configuration of the SNPP server process; see
		   the PriorityMap parameter in	hfaxd(8C)

       -n	   Send	to a numeric-only paging device; i.e. do  not  send  a
		   text	message	in the paging request.

       -N	   Do  not  notify the sender by electronic mail when the page
		   has been delivered to the service provider (default).  This
		   option is meaningful	only when communicating	with a HylaFAX
		   server.

       -p PIN	   The Pager Identification Number (PIN) for a	terminal  that
		   is to receive the message.  A message can be	sent to	multi-
		   ple destinations by specifying multiple -p options.

       -q	   Mark	pages to be queued on the server and do	not  wait  for
		   their  delivery.   By default sendpage conforms to the SNPP
		   spec	by synchronously waiting for each page	to  be	deliv-
		   ered.   This	 option	 instructs  sendpage  to submit	one or
		   pages and then terminate immediately	 without  waiting  for
		   their completion.  When pages are queued it is advisable to
		   enable email	notification with the -D or -R	options.   Job
		   queueing is a non-standard function of the SNPP implementa-
		   tion	in HylaFAX and is not available	when submitting	 pages
		   to non-HylaFAX servers.

       -R	   Enable notification by electronic mail when the message has
		   been	delivered and when it is requeued for  retransmission.
		   HylaFAX will	always notify the sender by electronic mail if
		   there is problem delivering a  page	(irregardless  of  the
		   email  notification	setting).   This  option is meaningful
		   only	when communicating with	a HylaFAX server.

       -s subject  Set the ``subject'' for the specified  pages	 according  to
		   subject.   For  HylaFAX  subject  is	used as	the identifier
		   string returned in any email	notification messages (instead
		   of the usual	job identifier number).	 This option is	useful
		   for applications that cross reference notification messages
		   against job submissions.

       -t tries	   Make	 no more than tries attempts to	send the page.	By de-
		   fault, HylaFAX will terminate a job if: 3  consecutive  at-
		   tempts to send a particular message fail, or	it appears the
		   receiver is not  a  service	provider.   Otherwise  HylaFAX
		   places  no  limit on	the number of attempts to send a page,
		   instead terminating a job if	it is not completed  within  a
		   fixed  period of time specified by the service level.  Note
		   that	a try is a phone call in which carrier is  established
		   and	the IXO/TAP or UCP protocol is commenced; this is con-
		   trasted with	a call attempt that might have failed  because
		   the	line  was  busy.   This	option is meaningful only when
		   communicating with a	HylaFAX	server.

       -T dials	   Make	no more	than dials phone calls when attempting to send
		   a  page.   By  default, HylaFAX will	terminate a job	if: 12
		   attempts to reach a service provider	fail,  or  it  appears
		   the	receiver is not	a service provider.  Otherwise HylaFAX
		   terminates a	job if it is not completed within a fixed  pe-
		   riod	 of  time specified by the service level.  This	option
		   is  meaningful  only	 when  communicating  with  a  HylaFAX
		   server.

       -v	   Trace  the  protocol	 between  sendpage and the SNPP	server
		   process that	does the delivery work on the remote  machine.
		   This	information is directed	to the standard	output.

CONFIGURATION PARAMETERS
       sendpage	 reads	configuration  information  from  the  files  /usr/lo-
       cal/lib/fax/hyla.conf, /usr/local/lib/fax/sendpage.conf,	and ~/.hylarc;
       in that order.  Configuration files follow the conventions described in
       hylafax-client(1).  The following configuration parameters  are	recog-
       nized:
       Tag	       Type	  Default      Description
       HoldTime	       string	  -	       hold time to assign to pages
       Host	       string	  localhost    host to contact for service
       MailAddr	       string	  -	       mail address for	notification messages
       MaxDials	       integer	  12	       times to	retry dialing
       MaxTries	       integer	  3	       times to	retry transmission
       Notify	       string	  none	       control email notification
       Port	       integer	  444	       port to use in contacting server
       Protocol	       string	  tcp	       protocol	to use in contacting server
       QueueSend       boolean	  No	       whether or not to queue pages
       RetryTime       string	  -	       delay between failed attempts to	send
       ServiceLevel    integer		       SNPP service level for pages
       Verbose	       boolean	  No	       whether or not to enable	protocol tracing

       The configuration parameters are	explained below:

       HoldTime	      The hold time to assign to pages.	 (Equivalent to	the -a
		      option.)

       Host	      The host to contact for service.	(Equivalent to the  -h
		      option.)

       MailAddr	      The  electronic mail address to direct notification mes-
		      sages from the server.   If  this	 string	 is  specified
		      without  an  ``@hostname''  part then the	local hostname
		      will automatically be appended.  (Equivalent to  the  -f
		      option.)

       MaxDials	      The  maximum  number of times to dial the	phone for each
		      job.  (Equivalent	to the -T option.)

       MaxTries	      The maximum number of times  to  retry  sending  a  job.
		      (Equivalent to the -t option.)

       Notify	      Control the email	notification messages from the server.
		      This string may be  one  of  ``done'',  ``none'',	 ``re-
		      queued''	or  ``default''	 with  an optionally preceding
		      ``when ''	(e.g. ``when done'').  Note  that  ``when  re-
		      queued''	implies	``when done''.	(Equivalent to the -D,
		      -R, and -N options.)

       Port	      The network port to contact for service.	(Equivalent to
		      the -h option.)

       Protocol	      The  name	of the communication protocol to use when con-
		      tacting a	server.	 (Equivalent to	the SNPPSERVICE	 envi-
		      ronment variable.)

       QueueSend      Control  whether	or not to wait for the pages to	be de-
		      livered.	(Equivalent to the -q option.)

       RetryTime      The time to delay	between	job retries due	to a  communi-
		      cation failure.  (Equivalent to the -I option.)

       ServiceLevel   The SNPP service level to	assign to each page.  (Equiva-
		      lent to the -l option.)

       Verbose	      Control protocol tracing.	 (Equivalent  to  the  -v  op-
		      tion.)

ENVIRONMENT
       The following environment variables are used by sendpage:

       SNPPSERVER     The  identity of the SNPP	server to contact for service.
		      This value is specified as ``[modem@]host[:port]'' where
		      host  is	either a host name or the Internet ``.'' (dot)
		      address of the host; port	is the TCP port	number or ser-
		      vice name	to use (default	is ``snpp'' or 444); and modem
		      is an optional modem name	or class on the	server machine
		      to  use  in  processing the requests (this is meaningful
		      only when	the server is running HylaFAX).

       SNPPSERVICE    The communication	service	specification for  communicat-
		      ing  with	 the  SNPP server.  This value is specified as
		      ``port[/protocol]''; by default ``444/tcp''.

FILES
       /var/spool/hylafax/tmp/sndpageXXXXXX    temporary files

NOTES
       The phone number	of the pager service provider is stored	on the	server
       machine	and  is	 not  specified	 by the	user; this is a	departure from
       pager support that was supplied with HylaFAX version 3.0.

       HylaFAX version 3.0 used	to recognize a null text  message  and	assume
       the  destination	 paging	 device	 was  numeric-only.  This is no	longer
       true; if	a null text message is submitted then a	null message  will  be
       included	in the paging request.	This may cause paging requests submit-
       ted to ``real SNPP'' servers to be rejected if the paging device	is  in
       fact numeric-only.  When	sending	to a numeric-only paging device	the -n
       option should be	used.

BUGS
       It is not possible to page text-	and non-text devices  together;	 send-
       page  must  be run twice, once to send to text-capable devices and once
       to send to non-text devices.
