	information.

2002-07-17 13:28  paschal

	* scripts/ptal-init.in: Changed all instances of "ptal-init" and

	functionality.	Minor updates to other files.

2002-07-16 10:07  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Added display of transport mode (MLC
	or 1284.4) to "successfully activated" message.  Split sending of
	fake Init packet in llioDrainReverseData into separate llioWrite()
	calls for header and data.  Moved calling of llioGetDeviceInfo and
	llioGetProtocols from llioSetup to llioGetDeviceID, because their
	results are needed in parseDeviceID.

2002-07-14 19:28  paschal

	* apps/cmdline/ptal-printd.c: Added a second underscore in the
	delimiter for the -morepipes additional pipe index, to prevent
	clashes between devices such as hpjd:jdex and hpjd:jdex:2.

2002-07-14 19:26  paschal

	* apps/cmdline/ptal-connect.c: Moved the -dump option lower in the
	list.

2002-07-14 14:22  paschal

	* apps/cmdline/: hpojip-test.c, ptal-devid.c, ptal-pml.c: Added
	missing extra newlines between error and syntax messages.  Fixed
	ptal-devid and ptal-pml so they properly handle -help option.

2002-07-12 06:52  paschal

	* scripts/ptal-init.in: For the sake of custom parallel-port probes
	on FreeBSD, changed to suggest a valid device node, with fallback
	to "/dev/lp0".

2002-07-12 06:06  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Changed to do simpler llioOpenOne()
	(without retry) if llioPossibleNameCount<=1 (not just ==0).  Added
	O_NONBLOCK to open(llioName) and wrapped this with alarm(2) to
	prevent infinite blocking on FreeBSD if no device is connected. 
	Fixed log messages in llioOpenOne so null llioName isn't passed to
	printf.

2002-07-12 05:09  paschal

	* scripts/ptal-init.in: Added blank line before "Stopping" and
	after "Starting" messages so the bootup messages look better on
	FreeBSD.

2002-07-11 09:52  paschal

	* configure, configure.in: Changed to better hide "sane-config: not
	found" error messages.

2002-07-10 20:35  paschal

	* configure, configure.in: Added /usr/X11*/lib/sane to
	SANE_BACKEND_DIR_POSSIBILITIES.

2002-07-10 20:06  paschal

	* Makefile.in, configure, configure.in: Changed to detect
	sane-backends (and more robustly) in configure script, not
	Makefile.  Added creating /usr/local/etc/rc.d/ptal-init.sh symlink
	for FreeBSD startup.  Fixed some incorrect "$(LN_S) -f" in
	Makefile.  Made lack-of-chkconfig message more user-friendly. 
	Added non-root messages of what to do about installing
	libsane-hpoj.  In configure script, added missing "break" when
	found CUPS backend directory.

2002-07-10 11:19  paschal

	* apps/cmdline/ptal-hp.c, apps/cmdline/ptal-photod.c,
	include/ptal.h, lib/ptal/ptal-mfpdtf.c, lib/sane/hpoj.c,
	lib/sane/hpoj.h: Added "__attribute__((packed))" to wire-data
	structures and unions.

2002-07-10 11:13  paschal

	* lib/sane/Makefile.in: Added sane.h and saneopts.h to INCLUDES
	list (for dependency checking).

2002-07-09 18:35  paschal

	* scripts/ptal-init.in: Added place in code to add more options to
	pass to ptal-mlcd probe.  Added config-file version checking and
	obsolete-device functionality.	Changed to put/remove ptal-init
	file in either /var/lock/subsys or /var/lock.  Reworked how unique
	devices are determined/handled with respect to model name, serial
	number (new), and parallel-port base address, in order to be more
	robust about having more than one instance of the same model or
	moving a device from one parallel port to another.  Long version of
	model/sernum now used throughout except for display purposes. 
	Changed cardReaderDetected so it verifies HP-CARD-ACCESS support
	after discovering it in the supported-functions PML object, in
	order to disable ptal-photod on LIO-connected OfficeJet D series. 
	Added confirmation prompt before replacing mlc: device names. 
	Added automatic deletion of old mlc:par: devices with same base
	address as a new device that gets set up.  Added verification of
	valid/defined device name before setting it as default.  Various
	code, comment, user interface, and file format
	cleanups/enhancements.

2002-07-08 18:05  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Changed llioDrainReverseData() to wait
	the full timeout (.5sec) even for USB, instead of timing out early
	given enough (4) zero-byte packets.

2002-07-05 19:21  paschal

	* apps/xojpanel/: xojpanel.cpp, xojpanel.h: From Joe Piolunek:
	Changed vertical text spacing back to constant (rather than
	centered) to better accomodate anti-aliased fonts in some
	situations.  Various code/comment formatting changes.

2002-07-05 15:45  paschal

	* scripts/ptal-cups.in: Fixed copy-and-paste error with labeling
	command-line arguments in debug output.

2002-07-05 07:26  paschal

	* apps/cmdline/ptal-connect.c, apps/cmdline/ptal-printd.c,
	lib/ptal/ptal-hpjd.c, lib/ptal/ptal-mlc.c, scripts/ptal-cups.in:
	Changed both ptal-connect and ptal-printd to have -uel and -nouel
	switches, with -nouel now the default.	Added -infretry and
	-retrydelay switches to ptal-connect and ptal-cups.  In libptal, a
	negative retryCount now means an infinite connect timeout.  Changed
	ptal-hpjd.c so "connection refused" errors are subject to the
	"short" (or infinite) timeout.

2002-07-04 19:30  paschal

	* Makefile.in: Added scripts/ptal-cups to file list for
	check_generated.

2002-07-04 10:21  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Reworked reverse data drain to apply
	to both parallel and USB.  Added -nodrain option to optionally
	disable channel-78 reset and reverse data drain.  Hid -hotplug
	option from help message.  Shortened the channel-78 reset delay for
	parallel, due to the added delay for reverse data drain.

2002-07-04 08:30  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Removed unused (and now incorrect)
	''socketPrefix[]="/dev/ptal-mlcd/"''.  Added setting most fake
	sockets to blocking mode when -remconsole is specified.

2002-07-03 20:12  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Changed forward data and command reply
	timeouts from 15 to 5 seconds.	Fixed LOG_INFO of received data
	count to actual rather than expected count.  Added USB drain
	reverse data to llioSetup.  Cleaned up some TODOs.

2002-06-27 10:59  paschal

	* mlcd/ExMgr.cpp: Fixed bug I introduced in the last checkin where
	application requests to close a channel would be lost if forward
	data was still pending.  Doh!

2002-06-22 12:54  paschal

	* lib/hpojip/xscale.c: Separated "p1++; p2++;" from references to
	avoid a gcc-3.1 compiler warning.

2002-06-21 14:46  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Added "forceclose" debug-console
	command to test ExTransport ability to flush forward data when
	closing a channel.

2002-06-21 14:45  paschal

	* mlcd/transport/: ExMlcCommandChannel.cpp, ExMlcTransport.cpp,
	ExMlcTransport.h, ExTransport.cpp, ExTransport.h: Updated copyright
	years to 2002.	Moved
	"pDataBdr->setTransportHeaderFlags(header->control)" to after the
	place which ensures that pDataBdr is non-NULL.	Removed "#ifndef
	ATTRIBUTE_PACKED" from "#define ATTRIBUTE_PACKED...".  Added
	optional ability for close() to flush buffered forward data.

2002-06-18 17:25  paschal

	* Makefile.in: Updated .PHONY target, which was missing some items.
	 Split just_install into user_install and root_install (at Mark
	Purcell's request).  Changed "test ! -z" to "test -n".

2002-06-17 12:36  paschal

	* Makefile.in, configure, configure.in, scripts/ptal-cups.in:
	Integrated Mark Horn's ptal-cups backend.

2002-06-14 12:19  paschal

	* lib/sane/hpoj.c: Disabled batch-scan option for OfficeJet LX and
	300 series.  Generalized SANE_CAP_INACTIVE checking for
	SANE_ACTION_SET_VALUE.

2002-06-14 11:49  paschal

	* configure, configure.in, apps/cmdline/Makefile.in,
	apps/cmdline/ptal-device.c: Added ptal-device command to simply
	list known PTAL device names.

2002-06-14 10:58  paschal

	* lib/ptal/ptal.c, mlcd/ExMgr.cpp: Added trapping (ExMgr.cpp) and
	ignoring (ptal.c) of SIGHUP (hangup signal).

2002-06-13 11:02  paschal

	* configure, configure.in: Added missing double quotes around [if
	test -n "$QT_MOC" -a -n] "$QT_INCLUDE_PATH".  Added commented-out
	debug statements.

2002-06-13 10:42  paschal

	* configure, configure.in: Moved AC_ARG_WITH stuff to the
	respective (SNMP, QT) sections.  Added --help explanation of
	--without options.  Added ability to override /var/run prefix. 
	Changed --without-{snmp,qt} to say "check not done" instead of "no:
	...".  Added placeholders for SANE and CUPS detection.	Largely
	rewrote QT detection (heavily modified from Joe Piolunek's patch). 
	Added --with-qt-moc, --with-qt-includes, QTDIR.  QT includes should
	now be found in /usr/X11R6/include/qt2.  Added recognition of
	libqt-mt.so.  Rearranged AC_SUBST and echo of variables at the end
	of the file.  Added warning messages about disabling
	JetDirect/xojpanel support due to a lack of SNMP/QT support.

2002-06-13 10:40  paschal

	* apps/xojpanel/Makefile.in: Changed to get -lqt[-mt] from
	configure script.  Split "HEADERS" into "COMMON" and "ALL" for
	proper dependency checking.

2002-06-12 13:50  paschal

	* Makefile.in: Added .PHONY target.  Changed *.in-update-checking
	implicit rule to an explicit shell routine, because the implicit
	rule wasn't working very well for some reason.	Added checking for
	updates to configure.in and configure.

2002-06-12 12:04  paschal

	* Makefile.in: Changed to detect changes to *.in files and force
	the user to re-run the configure script.

2002-05-23 08:46  paschal

	retry count is exhausted.

2002-05-18 10:26  paschal

	* lib/sane/: hpoj.c, hpoj.h: - Instrumented divideAndShift() to
	check for roundoff error.  - Moved length-measurement option before
	other geometry options.  - Added "unlimited" length-measurement
	choice, which disables br-y option.  - Changed default maximium
	extents for PML scanners to 9"x15".

2002-05-16 14:10  paschal

	* apps/cmdline/hpojip-test.c, include/hpojip.h, lib/hpojip/xpad.c,
	lib/sane/hpoj.c, lib/sane/hpoj.h: libhpojip, hpojip-test: - Added
	minimum-input-height parameter to X_PAD image transform.
	
	libsane-hpoj: - Added length-measurement option.  - Fixed bug where
	last data buffer was getting lost in sane_hpoj_read,   because
	SANE_STATUS_EOF was overridding it.  - sane_hpoj_read now sets

	scanning support for OfficeJet LX and 300 series.  Added optional
	saving of compressed (MFPDTF stripped) scan data to a file. 
	Changed geometry options from integer to fixed-precision type. 
	Removed redundant variables in image-dimension handling.  Increased
	MFPDTF_LATER_READ_TIMEOUT from 10 to 20 seconds to prevent timeout

2002-05-04 13:11  paschal

	* mlcd/ParPort.cpp: Made more tolerant of terminate() failures at
	event 23.

2002-05-03 14:17  paschal

	and lp only when probing those connection types.  Made non-root and
	syntax-error messages the same (including &printDeviceList).

2002-04-28 13:20  paschal

	* apps/cmdline/ptal-printd.c: Changed to open print channel after
	reading first packet of print job data.  After too many "empty"
	jobs are received, sleeps for 2 seconds, because select() on a FIFO
	never seems to block on FreeBSD.  Added pipeBaseName to
	syslog("successfully initialized") message.

2002-04-28 11:01  paschal

	* lib/sane/: hpoj.c, hpoj.h: Added resetting of PML scanners in

2002-04-28 10:04  paschal

	* mlcd/ParPort.cpp: Added clearing of CONTROL_REVERSE_DATA bit in
	negotiate() and terminate() to fix bug where ptal-mlcd had to be

	bidirectional or ECP parallel port.

2002-04-26 09:07  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Moved device ID parsing (and transport
	determination) to before llioSetup() is called.

2002-04-24 09:25  paschal

	* lib/sane/hpoj.c: Removed SANE_CAP_AUTOMATIC, because it already
	automatically sets options when needed.  Added notes of where to
	add more calls to hpojScannerIsUninterruptible.

2002-04-23 13:56  paschal

	* doc/setup-scan-details.html: Added note about not being able to

	ptal-stop.conf.  - (Hopefully) fixed "make install" so it installs
	symlinks correctly on FreeBSD.	- Moved /dev/ptal-{mlcd,printd} to
	/var/run, with a /dev/ptal-printd   compatibility symlink.  -

	default-device and new device registry capabilities into libptal,  
	ptal-init, libsane-hpoj, and most cmdline apps.  - Cleaned up
	libptal and cmdline apps error messages.  - ptal-connect now says
	when it's trying to connect and succeeds/fails (with   a -quiet
	option).  - Lots of general code and command-line syntax message
	cleanups.  - Added -bindto and -bindtoall to ptal-photod to specify
	which network	interface(s) to bind to (or all).  - Added
	-maxaltports to ptal-photod to try incremental port numbers if the 
	 default port number is already taken (and report final port number
	in   startup syslog message).  - libptal now ignores SIGPIPE.  -
	Added -morepipes to ptal-printd to create additional FIFOs and
	round-robin   between them for different print queues.	- Updated
	documentation to reflect new functionality and split into basic  
	and detailed setup information.  - Moved some functions around in
	libsane-hpoj.  - Removed SANE_HPOJ_DEVICE from libsane-hpoj.  -
	Added higher (safer) default JPEG compression factor for OfficeJet 
	 500/600/700 and PSC 300 series to libsane-hpoj.  - Added to
	libsane-hpoj and ptal-mlcd recognition for Sony   "All-in-One
	IJP-V100" (OEM of HP OfficeJet 500 series).  - ptal-mlcd can now
	handle "mlc:" prefix on its device name parameter.  - Added "use
	strict" to ptal-init, split into more subroutines.  - Added
	parallel, JetDirect, and ptal-photod setup and FreeBSD support to  
	ptal-init.

2002-03-25 13:45  paschal

	* apps/cmdline/ptal-hp.c: Removed "Total RAM size" query from

	mlcd/ExMgr.cpp, mlcd/ExMgr.h, mlcd/mlcd.h, scripts/ptal-init.in:
	Added capability for ptal-mlcd to store and libptal,ptal-devid to
	retrieve the previous device ID string before a deactivation. 
	ptal-init uses this to indicate that it found a device but was
	unable to communicate with it.
	
	ptal-mlcd: Added -log,-logwarn,-nolog switches.  Zero out
	session[scd].tcd pointers at deactivation.  When reading data in
	llioService, moved r!=datalen check after dumping the buffer.
	
	ptal-init: Added usbWildcard list, automatic determination of the
	right one, and error message if none of them worked.  Added elapsed
	time printout in communication-failure case so I can know from a
	log if there was a 15-second reply timer pop.

2002-03-23 14:57  paschal

	* lib/sane/: hpoj.c, hpoj.h: If a PML scanner is in a state where a

	No more annoying file-extension rewriting! Cleared out
	SCAN-UPLOAD-ERROR before starting scan (for LaserJet 1100A).  Added

	* apps/xojpanel/: xojpanel.cpp, xojpanel.h: From Joe Piolunek: 1.
	If the user builds the application with a choice of a very large or
	very small font to be used in the 'LCD' message window, the text
	will be vertically centered a little better.
	
	2. It adds the ability to do 'special character' translation.  At
	present, the user will need to specify the desired character
	translations ( at the top of apps/xojpanel/xojpanel.cpp ). In the
	future, it may be possible to enable several by default, but right
	now I don't know which one(s) can be used without causing potential
	conflicts.
	
	From David Paschal: Added "characterTranslationMap[255] = 0x20;"

2001-10-20 20:24  paschal

2001-07-15 18:11  paschal

	* mlcd/ExMgr.cpp: In exDeactivate(): Added 1-second delay after
	llioClose to try to prevent USB crashes on reactivation.  Moved

	root-specific install section.	Added warning message if SysV init
	script directory not found.  Added warning message if chkconfig not
	available.  For root, adds libdir to /etc/ld.so.conf if not already
	there and runs ldconfig; otherwise, prompts user to do this
	manually.  Checks for outdated files from previous versions and
	prompts user to delete.  In *.conf, improved some wording and added
	place to modprobe printer.

	static const" kludge.  Added "static const member definitions" to
	ExTransport files (from a co-worker; I don't know if I need to do
	this in ExMgr and ParPort also).

2001-07-06 19:49  paschal

	checking in!  :-)

2001-07-06 19:08  paschal

	Fixed jpegDone so it doesn't wait if it appears that there's
	nothing to wait on.  Changed scan upload timeout from 120 to 45
	seconds.  Turned on read timeout, now that the ptalChannelSelect()
	bug is fixed.  Added multi-page scanning, including -multi,
	-pagenum, and -pagenumdigits.  Fixed problem with scanning more
	than one page on the LaserJet 3200 and 1220, where we are forced to
	read the NEWPAGE state and decide on the new state (START or IDLE)
	before we get the end of page record.  Adds .pnm or .jpg extension
	if no extension is given.  Changes .pnm or .jpg extension if the
	one given mismatches the compression setting.  Rearranged some

2001-06-27 22:15  paschal

	* apps/cmdline/xjpg_dec.c: First checkin, with my hacks to extract

2001-06-27 22:07  paschal

	* apps/cmdline/ptal-hp.c: Added counting of raster lines in

	Yes, I know that you're supposed to compile .c files separately,
	not #include them like .h files.  :-)

2001-06-27 21:59  paschal

	* SCAN-HOWTO: Added information about ptal-hp's new ability to
	automatically detect image height and to adjust with a -length
	delta.	Added warning that changing the default resolution in
	certain situations may lock up the scanner.

2001-06-24 16:54  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Moved initialization of grouped
	attributes (socket, llio) out of the ExMgr constructor into
	separate functions called by the constructor.  Added support for
	multiple -device switches and multiple parameters to a single
	-device switch, to support shell-globbed args like "/dev/usb/lp*". 
	Added -devidmatch to specify substrings to match in the device ID
	string.  Renamed -devid to -devidset.  Changed llioOpen to loop
	through all devices until it finds one whose device ID string
	matches appropriately.	In case other instances are doing the same
	thing, delays a random amount of time and retries device nodes that
	haven't already been opened.  errno==EIO in llioRead is now
	converted into no data read instead of causing an immediate
	deactivation.

2001-06-19 10:29  paschal

	* mlcd/: ExMgr.h, transport/ExMlcTransport.cpp,
	transport/ExTransport.h: Added stub functionality for setting
	MLC/1284.4 header control field.  Fixed bug with lost reverse
	credit after failed MLC (not 1284.4) channel open.

2001-06-18 19:51  paschal

	* mlcd/ExMgr.cpp: Fixed "fdRegister(invalid fd=-1,r=1,w=0) called
	from ExMgr.cpp:2079" error, by not calling fdRegister if a channel
	is in SESSION_STATE_OPEN_PENDING.

2001-06-18 19:20  paschal

	* apps/cmdline/ptal-hp.c, include/ptal.h: Moved
	[BL]END_[GS]ET_{SHORT,LONG} macros from ptal-hp.c to ptal.h.

2001-06-15 08:27  paschal

	* mlcd/ExMgr.cpp: Fixed logging of sleepBeforeOpen.

2001-06-13 21:20  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Added LOG_SYSLOG macro that logs to
	syslog but not the console, unless console log level is LOG_WARN or
	higher.  Joined two log lines for syslog to prevent lines from
	multiple instances from getting interleaved.  Added LOG_SYSLOG for
	successful initialization and activation.  Added OK/ERROR return
	value for _fdRegister and a debug error log message after one
	particular call that is happening occasionally at the wrong time. 
	Changed syslog facility from daemon to lpr.

2001-06-13 20:51  paschal

	* apps/cmdline/ptal-printd.c: Changed syslog facility from daemon

2001-06-12 18:49  paschal

	* mlcd/ExMgr.h: Fixed segfault when connecting to PTAL-MLCD-DEVNODE
	without a "-device" setting, which can occur with parallel.

2001-06-12 17:51  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Turned warning messages off by
	default, added "logwarn" console command to turn them back on. 
	Changed the "important" warnings to errors.  Fixed some log
	messages and dump printfs.  Sanitized JD_DEBUG usage, converted
	LOGD_* to LOG_*.  Added pid to dump() and "pid" debug console
	command.  Rearranged some attributes and methods in ExMgr class. 
	Removed select() xsets, which were disabled anyway.  Substituted
	/dev/null for a closing transport session, as well as for the PML
	transport session.  That makes the code path simpler because we can
	brainlessly write data to such sessions without having to check for
	the lack of a file descriptor (but check for the state instead). 
	Changed the forward and reverse data paths so that queued outgoing
	data is only sent from exMain().  This prevents channel/direction
	starvation and makes the debug console more available.	Generalized
	sessionInWrite attribute into exContext enum.  Added transparent
	file/line passing to fdRegister, to make it easier to debug errors
	about an invalid fd passed to this function.  Rearranged some
	things to make the code more compact and remove redundancies,
	especially regarding service state transitions and discarded data
	due to channel close.  Changed LOG_ERROR_FATAL to LOG_ERROR in
	sessionPostSelect() due to an invalid state.  Added macros
	containing common code for special sockets.  Added special sockets
	for pid, device node, and command line.  Added simulated service
	name lookup for special sockets.  Fixed sessionServiceOutput()
	handling of when the socket write fails, to prevent an
	inappropriate channel close (if errno==EAGAIN) and a buffer leak. 
	Fixed unprepend call in sessionServiceOutput to prevent data loss. 
	Scan cancel and scanimage --test should now work on OfficeJet
	Pro/R/PSC500.  Added LOG_NDELAY flag to openlog() so syslog
	connection is made at startup.	Added dump() method for QueueEntry
	class.	Increased maximum outstanding forward transactions.

2001-06-12 11:20  paschal

	* apps/cmdline/ptal-printd.c: Added LOG_NDELAY flag to openlog()
	call, so syslog connection is made immediately.

2001-06-08 05:25  paschal

	* configure, configure.in: Changed test for libqt.so from -x to -f,
	since shared libraries don't have to be marked as executable.

2001-06-05 20:06  paschal

	* mlcd/ExMgr.cpp: Added checking for a live socket (used by another
	process) before recreating it.

2001-06-05 19:28  paschal

	* apps/cmdline/ptal-connect.c: Added -fwdlen and -revlen options to
	adjust requested max packet sizes (not including the MLC/1284.4
	header, of course).  Removed display of predefined devices, since
	currently there are none.

2001-06-05 19:10  paschal

	* configure, configure.in: Added support for QT installed under
	/usr/bin, /usr/lib, and /usr/include/qt.  Converted individual
	AC_CHECK_HEADER macros to one long AC_CHECK_HEADERS macro that
	prints a warning if any file couldn't be found.

	(which previously caused exit).  Added logging of errors to syslog.
	 Added workaround for lack of stdio FDs when invoked from a hotplug
	script.  Added typical invocations to syntax message.

2001-06-05 17:53  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Worked around lack of standard I/O FDs
	when invoked from a hotplug script.  Added logging to syslog.

2001-06-03 15:21  paschal

	* include/ptal.h: Moved PTAL_DEFAULT_RETRY_COUNT and _DELAY from
	ptal.c to ptal.h.  Added PTAL_SHORT_RETRY_COUNT.

2001-06-02 17:46  paschal

	* mlcd/ExMgr.cpp: Special-cased OfficeJet 500 through T series for
	bounded ECP (bidi-ECP18).  Special-cased OfficeJets C2890A, LX, 3xx
	for credit miser and ECP10+nibble.  (I don't know if I used the
	correct MDLs for C2890A and LX.) Added warning message about SPP
	unless "-porttype spp" is given.

2001-06-02 17:42  paschal

	* mlcd/ParPort.h: Added missing setting of currentChannel in
	writeEcpChannel().

2001-05-31 18:13  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Changed ExBdr::nextInChain references
	to use getNext/setNext methods.  Changed "-activate" switch to
	"-hotplug", which activates on startup and after each deactivation
	and exits on activation failure.  This flag also enables a 1-second
	delay before calling llioOpen to try to prevent crashes which may
	stem from re-opening too soon during handling of an unplug event. 
	Fixed fatal error in ExMlcTransport caused by
	llioForwardBdrQueue->empty() in llioClose(); changed this to pull
	each BDR chain out of the queue and call
	pBdr->getTCD()->forwardDataResponse.

2001-05-30 10:35  paschal

	* configure, configure.in: Cleared ac_cv_lib_snmp_snmp_open from
	cache so "-lsnmp -lcrypto" will get detected properly.

	after abort label.  Changed to abort if an unknown device (neither
	OfficeJet nor LaserJet) is specified.  Fixed printing of default
	pixelDataType.	Added -length switch to override the JPEG
	length-guessing kludge.

2001-05-05 12:44  paschal

	rowCount to JPEG child process and for child process to rewind the
	file and write out the rowCount.  Added recognitition of standard
	JFIF header input.  Changed default pixelDataType to COLOR, except

2001-04-12 09:29  paschal

	* mlcd/: ExMgr.cpp, ExMgr.h: Changed to assume 1284.4 if MLC for
