+Commit: a513c36
+Detect client EOF properly. Handle EWOULDBLOCK.
+
+Client disconnection appears as a read of 0 bytes.
+Without a test for this, dump1090 continues to poll that client forever.
+
+Also, read() may return EWOULDBLOCK as well as EAGAIN
+for "no data right now", so handle that.
+
+I don't know if there is an equivalent Win32 bug here as the Win32
+interfaces seem subtly different to vanilla POSIX.
+
+The following test/break can probably be removed if Win32 needs
+the same fix.

+Commit: 661246d
+Prefer to use global CPR decoding where possible.
+
+There is a danger in always using relative decoding where possible.
+If there is an undetected error in the first pair of messages received,
+then global CPR decoding will give a bad position, and subsequent
+relative decoding will just walk around near that bad position even
+though many error-free pairs of odd/even messages may have been received.
+
+The first pair of position messages also tends to be the most error-prone, as
+they are usually received at the extreme edge of receiver range.
+
+(I see this happen at least once a day in practice)
+
+So, instead, prefer to use global decoding when we have sufficiently recent data.
+With recent data this should always be as good as relative decoding, and it
+avoids getting stuck with bad data for long periods of time. If we don't have
+enough recent data for a global solution, fall back to relative decoding.
+
+Oliver Jowett <oliver at mutability.co.uk>
+
+
+Commit: e5b3572
+Reject out-of-range latitudes when doing CPR decoding.
+
+If a CPR message with an undetected error is received this can produce out-of-range results for latitude.
+e.g. even latitude of 78000, odd latitude of 0 produces a latitude index j=35 and rlat0 = 213.

+Commit: 903f93f
+Publish Version 1.08.2705.14
+
+A few minor additions and bug fixes as detailed below
+
+1) Additional command line option "--net-buffer <n>" to specify the TCP
+output buffer size. Default is n=0, which is 64Kb. Specify a value of n
+to increase the buffer size according to Size = 64Kb * 2^n, so an n of
+1 = 128Kb, n=2 is 256Kb etc. n is limited to 7, so the max size is 8Mb.
+This option may assist if you have a high number of aircraft being
+received, and an unreliable network connection, or if the receiving end
+can be busy for an extended time.
+
+2) Bug fix in ppup1090 which prevented the uploading of valid
+ModeA/Squawk codes
+
+3) Bug fix per Markus Grab's commit.

+BUGFIX : Possible linked list bug
+
+Malcolm Robb <Support at ATTAvionics.com>
+
+
+Commit: 30ae45e
+Windows Version of dump1090
+
+Make the modifications necessary to compile dump1090 for WinXP, Win7 and
+hopefully Win8.
+
+The files can be compiled using M$ Visual Studio/C++ 6.0. Due to various
+licensing issues, I haven't included the libraries or DLLs. You will
+need to locate pthreadVC2.lib and rtlsdr.lib to link the file, install
+the zadig drivers to support the dongle, and locate libusb-1.0.dll,
+msvcr100.dll, pthreadVC2.dll and rtlsdr.dll.
+
+dump1090.exe will not run on any Windows version prior to XP SP2,
+because msvcr100.dll imports several functions from the Windows kernel
+that are not available on earlier versions. This means dump1090 won't
+work on Win2K.
+
+The major change to the code relates to file handles. The original code
+assumes Linux behaviour in that handles are allocated from 0
+sequentially upwards. However Windows handles are allocated pseudo
+randomly, and handle numbers greater than 1024 would break the code. The
+code has therefore been modified to use a linked list of connection
+structures, rather than a static array limited to 1024 entries.
+
+Malcolm Robb <Support at ATTAvionics.com>
+
+
+Commit: f7843c1
+Implement TCP Heartbeat
+
+Some users have reported issues where the TCP link to dump1090 can be
+lost at times of low traffic density - typically in the middle of the
+night. One possible reason for this is that some routers drop the link
+if there is no traffic for a predetermined period.
+
+To try and resolve this, dump1090 now sends a 'null' packet consisting
+of 7 "0x00" bytes approximately once a minute if there is no real
+received traffic during this time. This packet should be discarded by
+the application receiving the dump1090 because it will have an invalid
+checksum, and ICAO address 0x000000 is also invalid. However, this null
+packet should be enough to keep routers alive.

+BUGFIX : Beast Binary Escape characters
+
+Thanks to Blort on the PP list.
+
+The Beast binary message stream uses the 0x1a character a and escape to
+mark the beginning of a new message. However, the 0x1a character could
+occur in the body of a message since the message is binary. Therefore,
+the 0x1a is repeated -as Blort put it :
+
+This 56-bit Mode S Frame (containing a 1a) is supposed to look like
+this:
+
+1a 32 00 00 48 7b a6 1a 1a 0c 20 28 17 b0 c0 c3 b0
+
+What is actually looks (looked) like (from wireshark) is this:
+
+1a 32 00 00 48 7b a6 1a 0c 20 28 17 b0 c0 c3 b0
+
+There are supposed to be two 1A’s (Gunter’s Escape Character) in a row
+(1A 1A) whenever a data byte contains 1A, after the initial two 1A 3x
+characters.

+Commit: 75a4c6e
+BUGFIX : Missed data causes timestamp slip
+
+The Mutex on the RTL data reader thread does not "force" the data
+processing thread to execute. Therefore, if the processor is busy, it is
+possible for a second RTL callback to occur before the data from the
+first has been processed. This will cause the loss of the first data,
+but worse, it will cause a slip in the timestamp. This upsets Beamfinder
+and MLAT operation in PlanePlotter.
+
+To solve this, keep a Fifo buffer which is filled by the callback
+thread, and emptied by the data processing thread. The fifo is the same
+size as the number of buffers requested in the call to
+rtlsdr_read_async().
+
+Note - we only put the value of the pointer supplied in the callback
+into the fifo. We do not attempt to cache the data in the buffer pointed
+to by the pointer. This would require us to memcopy() 2Mbytes per
+second, which we don't want to do if we don't have to because it will
+only make the processor loading worse. Instead, we assume that the data
+in the buffer will remain valid after the callback returns, at least
+until it is overwritten by new data.
+
+It is still possible for us to lose data if we can't process it quickly
+enough. However, we can now detect this loss of data when the fifo is
+almost full, and correct the timestamp for the lost block/blocks.

+If the aircraft lands or takes off, the Lat/Lon valid flags are cleared.
+In the original code, this also resulted in any even/odd position
+reports in the mm record being discarded This meant that the code would
+require an even and odd position after the change of flight status.
+
+The code had been modified so that any position report in the mm record
+is used even if there is a change of flight status. This means there
+only needs to be an even or odd after a change of FS, rather than
+requiring both even and odd. The result should be earlier decoding of
+position.

+DF-11 SI/II Detection changes
+
+Don't allow detection of DF-11 SI/II until we have received at least one
+DF-11 for the aircraft with an SI/II of zero.
+
+Previous versions would allow an ICAOAddr to be marked as valid if a
+DF-11 was received where the crc was less than 80. This is required for
+SI/II detection where the SI/II is overlaid on the crc field. However,
+this also decreaces the security of the crc. It is possible for a
+corrupt message to result in a crc value of between 1 and 79, and this
+will lead to an invalid ICAOAddr being marked as received.
+
+To try and prevent this, do not allow detection of DF-11 II/SI fields
+until at least one DF-11 crc=0 has been received. Once this happens, we
+ca be fairly sure that this aircraft really is within range, and so
+II/SI detection can e used.

+Stop heading using multiple lines
+
+In the table view of aircraft, the heading was displayed as "330 (NW)"
+or similar. However, this cause the entry to scroll over into two lines
+of text, and reduces the number of planes that can be seen in the table
+at any one time.
+
+There probably should be a way to make the table view wider by scrolling
+it, but I can't see any way to do that. So for the moment I've commented
+out the extra (NW) bit.

+IE 8/9 Bugs in Web interface
+
+*DISCLAIMER*
+I didn't write any of this code initially, I've never tried to use it,
+and I don't understand Java Script at all. In-fact I hate the wretched
+stuff.
+
+Anyway, it appears that no-one has bothered to test any of the Web
+interface code using Microsoft Internet Explorer 8 or 9. I've attempted
+to hack out the sections of the code that are causing problems, and at
+least the web interface now seems to run.
+
+However, for some reason the planes never move - I know this must be a
+bug, but I don't know how to fix it.
+
+Most of the errors relate to trailing commas. My guess it that some
+Java engines don't mind trailing commas, but that the Microsoft ones do.
+There are also some undefined modules (untrackedDeveloperSettings) and
+functions (console.log) which I guess those who wrote the code have on
+their machines, but forgot to include in the public distribution. I've
+no idea how to fix this, so I've just hacked them out of the code.

+Implement a remote interactive screen
+
+No changes to dump1090, (except the version number)
+
+Include a sample Linux batch start file called dump1090.sh for use when
+running dump1090 headless. This file needs to be copied to the
+/etc/init.d/ subdirectory on your raspberry pi, and marked as
+executable. Then when you re-start your RPi, dump1090 will start-up
+auto-magically and run as a sort of server to allow both local and
+remote connection to it's various internet ports.
+
+Modified the Makefile to build a new headless helper application called
+view1090
+
+Added view1090. This is an executable that allows you to connect to
+dump1090 when it is running and 'see' the interactive screen display.
+The default is to try and connect to dump1090 on IP address 127.0.0.1
+port 30005. This should work if you are running on the same RPi as
+dump1090 and using the default dump1090 port settings. However, if
+you're running on a different machine you will have to specify the IP
+address of the RPi running dump1090 using the --net-bo-ipaddr switch.
+Something like "view1090 --net-bo-ipaddr 192.168.2.65" . You may also
+have to sudo it, depending on your privilige settings.
+
+I've also compiled view1090 as a Wiin32 exe, so you should be able to
+run it under any 32 bit version of Microsoft Windows - i.e. Win95, Win
+2K, Win XP, Win 7 etc. It may work on Win 8 and 64 bit Windows, but I
+haven't tried it. The Win32 version is compiled from the same source, so
+takes all the same command line switches.

+Bug Fix in modesReadFromClient()
+
+The modesReadFromClient() funtion is called from modesReadFromClients(),
+which in turn is called from backgroundTasks(). backgroundTasks() is
+called from within the main processing loop.
+
+However, modesReadFromClient() can and does block. It attempts to read
+characters from the input stream, and loops whilst there was no error.
+This stalls the main RTL processing loop until an error occurs. In order
+to support simultaneous local reception (via our RTL dongle) and remote
+forwarding (data received from the interweb) we cannot allow this
+internet read to stall.
+
+To fix this, in modesReadFromClient() attempt to read a buffer of data
+(currently 0x400 bytes). If we get a full buffer of bytes, then process
+them, and attempt to read another full buffer. Keep doing thios untill
+we read only a partial buffer (less than 0x400 bytes). Process the
+partial buffer bytes and return.
+
+This allows us to occasionally process data that is arriving from the
+internet (which is buffered anyway in the TCP stack), without blocking
+local RTL dongle decoding.

+Split into separate module files
+
+Ok - this is likely to upset some people. Up until now, the vast
+majority of the code has been in just one file - dump1090.c. This file
+has grown so that it was approaching of 5000 lines long, and it was
+becoming unmanagable. So I've split the file into several modules,
+hopefully along fairly logical boundaries. The files are :
+
+1) dump1090.c : Basically just the main() entry function, the help
+function, the RTL dongle hardware interface, and a few orphan functions
+that don't really fit anywhere else.
+
+2) mode_s.c : This contains all the mode S / ADSB decoding functions.
+
+3) mode_ac.c : This contains all the mode A & C decoding functions
+
+4) interactive.c : This contains all the functions to maintain an
+internal list of aircraft seen over the last period, and functions to
+print them out to the local console.
+
+5) net_io.c : This contains all the network input/output functions
+allowing data to be passed in/out to/from other receivers, in formats
+such as SBS-1/3, Beast, AVR and JavaScript.
+
+Hopefully this should provide an easier way forward if/when more
+functions are added.

+
+1) Modes.interactive_display_ttl defines for how long the display of an
+aircraft persists after the last received message. The default is
+MODES_INTERACTIVE_DISPLAY_TTL, which is set to 60 seconds. This replaces
+the previous Modes.interactive_ttl/MODES_INTERACTIVE_TTL settings (which
+were also 60 seconds)
+
+2) Add an additional Modes.interactive_delete_ttl parameter, and
+default it to MODES_INTERACTIVE_DELETE_TTL, shich is set to 300
+seconds/5 minutes. This defines for how long an aircraft persists in the
+list structure after the last received message before being deleted.

+Commit: ee742cf
+SBS Output Format changes
+
+Bug fixes in the SBS output code as a result of an EMAIL from Liviu
+
+Some software gets upset if null fields are output where the software is
+expecting a valid value. This was being caused by DF0's outputting and
+SBS MSG5. MSG5 needs Atert and SPI flags, which are derived from the FS
+field. DF0 doesn't have an FS field, so cannot output a MSG5. Change so
+that DF0 results in an SBS MSG7.
+
+Also DF17/DF18 metypes 5 to 18 contain raw Lat/Lon data. However they
+cannot be decoded into real Lat/Lon values unless both even and odd
+parts are available Therefore, when we receive a DF17/DF18 we need to
+check that we have successfully decoded the Lat/Lon before we attempt to
+send an SBS MSG2 or MSG3. If we don't have a decoded Lat/Lon, send a
+MSG7 instead.

+mm structure initialisation
+
+Ideally we should clear down the mm structure every loop of our
+ModeA/C/S bit detector. However, we're getting 2Mbits of data per
+second, and the structure is several tens of bytes long. Clearing down
+every loop would require us to zero up to 100Mb per second. The memset
+function may be fast, but it's still going to take up valuable processor
+time.
+
+So instead of clearing the whole structure every loop, just clear the
+important parts.

+Change mm.crc checks to mm.correctedbits
+
+Instead of force clearing mm.crc to zero if we successfully correct bit
+errors, just use the mm.correctedbits variable. This allows us to print
+out the crc value containing the errors during list output modes.

+VK1ET : Use error corrected DF17
+
+Actually use the (DF17) messages where we do bit correction.
+
+Other changes to AVR message I/O.
+1) treat mlat timestamp of zero as invalid (easier to work with than
+(-1) and equally unlikely).
+2) If we don't have a valid timestamp send a without timestamp
+'*.......' message rather than '@.......' with invalid time.
+3) Drop interpretation of obsolete AVR ' #' & '$' formats - they
+wouldn't have worked anyway (wrong length).

+VK1ET : --Interactive display changes
+
+Based on a submission by VK1ET, but I've tweaked it a bit to use the
+bFlags.
+
+Basically, only print out values in --interactive that have been
+received from the aircraft. Previous versions would display 0.000 for
+lat and long for any positionless aircraft. This version prints blanks
+instead for any/all fields that are not yet known.

+Major Rewrite of SBS output code
+
+Remove dependency of the SBS output code on the historic (a) aircraft
+structure. The only items that were required were the decoded aircraft
+Lat/Lon and these are now included in the mm structure.
+
+Rewrite the SBS output code to use mm->bFlags when populating the output
+fields. This ensures that all available data is output, and also that no
+stale data is sent.
+
+Using the mm->bFlags variable for SBS output means there is no further
+requirement for the sbsFlags member in the aircraft structure, so remove
+it.
+
+Cross your fingers and hope this hasn't introduced too many bugs !

+Additional bFlags for Lat/Lon decoding

+Additional flags in the bFlags variables for even and odd CPR lat/lon
+updates.
+
+Change the interactiveReceiveData function to use the bFlags when
+updating the aircraft (a) structure from the newly received (mm) message
+structure. This should hopefully be faster than basically re-decoding
+the DF, type and subtypes all over again.
+
+If we decode the lat/lon into the aircraft (a) structure, back populate
+it into the message (mm) structure. This allows us to print a decoded
+Lat/Lon in the decoded message list output.

+Change Mode-A/C to Mode-S detection
+
+The original code made an attempt to reconcile a newly arrived ModeA/C
+message with every known Mode-S report at the time of detection.
+However, the results of matching up Modes A/C and S are only used in the
+interactive display routine, and that is only called periodically from
+within the BackgroundTasks loop.
+
+Doing the matching on every ModeA/C arrival incurs quite a large CPU
+processing load. Moving the matching up routine to the backgroundTasks
+loop means that the task is performed muck less frequently and therefore
+uses less CPU time.

+Implement Mode A/C decoding
+
+First attempt at decoding legacy SSR Modes A and C.
+
+If the command line switch --modeac is used, the program will now
+attempt to recover Mode A/C signals contained in the raw I/Q data
+stream. The current recovery mechanism is quite strict and does not cope
+well with overlapping and corrupt SSR replies. I estimate that less than
+20% of possible returns are decoded correctly. Hopefully over the next
+few iterations this can be improved.
+
+If outputting raw data it is recommended to use the --net-ro-size and
+--net-ro-rate command line options to reduce the number of very small
+ethernet packets that will be generated by mode A/C replies.

+Commit: 3d25f4b
+Changes to prevent stale output in SBS-1 format
+
+The original code calculates Lat/Long only if it receives two DF-17
+(subtype 9 or 18) within one second of each other. I have no idea why.
+It then caches the results in the aircrafts data structure for use in
+the --interactive display.
+
+When SBS-1 style ASCII output is selected (port 30003) the code does not
+attempt to calculate Lat/Long from the data just received - instead it
+picks it up from the cached information in the aircraft's data
+structure.
+
+However, if the data isn't being updated this results in stale Lat/Long
+being sent out. This is most likely to occur when the aircraft is at the
+extreme edge of the receivers range when it may be getting some DF-17s
+containing Lat/Long, but not 2 per second. The program will continue
+sending the stale data until the aircraft finally times out (default 60
+seconds)
+
+I have modified the code to include a sbsflags variable in the aircraft
+data structure. When a new Lat/Long is decoded and put into the
+structure, a bit is set to indicate SBS_LAT_LONG_FRESH. Then, once the
+Lat/Long is output the first time, the bit is cleared. Thereafter the
+code will not populate the Lat/Long fields in the output message until
+SBS_LAT_LONG_FRESH is set again.

+Added Raw Output Buffering
+
+The original code wrote every individual received frame to the TCP port.
+Some O/S's buffer smaller writes into larger packets. It appears that
+some versions of Linux don't. The result is that the (Ethernet) network
+gets bombarded with lots of small Ethernet packets.
+
+Therefore, I've added a 1500 byte output buffer to the raw output
+functions. Data is written into this buffer by the raw output routines.
+
+Data is flushed out to the TCP port when either.
+1) The latest write to the output buffer takes the contents to more than
+1300 bytes
+2) At the end of every processed block of data supplied by rtl-sdr. This
+will be every 56mS or so,
+
+The end result should be that on systems detecting a lot of traffic, you
+should see lots of > 1300-byte Ethernet packets. On systems receiving
+less traffic, you should see one network packet every 56 mS or so.
+
+The total number of network packets should be much reduced, and their
+average size much bigger. The worst case delay in transmission will be
+56 mS.

+Try to correct single bit errors in the DF field

+
+In such circumstances we assume the message length is long(112 bits)
+However, if we start to get encoding errors after bit 56 the we attempt

+Change the message bit decoder
+
+Change (and hopefully improve) the Message bit decoder.
+
+When decoding bits, a "0" is encoded as (m[j]<m[j+1]), and a "1" is
+(m[j]>m[j+1]) . However, there is a problem if mpj[ == m[j+1] because we
+can't decide what it's supposed to be.
+
+Antirez's original code defaults to a '1', and then lets the bit error
+detection code sort it out. I *think* it's better to default to '0'
+because it's more likely that noise added to the signal will produce a
+spurious '1' rathar than anything subtracting from the signal to produce
+a spurious '0'
+
+Also, Antirez''s code only looks for errors in the first bit of the
+message. I don't know why this is.
+
+There is a potential problem in deciding the message length if there are
+any errors in the first 5 bits decoded, because this defines the message
+type (the DF-??), and it's the DF that determines how many bits the
+message shall contain.
+
+If there is an error in the first 5 bits, then we could ignore the DF,
+and continue decoding a long format (112 bits). However, for weak
+signals, if the message is a short one (56 bits) this results in the
+sigStrength decaying to the point where it's level drops below squelch,
+so we discard a possibly decodeable 56bit
+
+However, if we assume it's a short message, and only decode 56 bits, and
+it's really a long message we won't have decoded all the bits.
+
+Not sure what to do about this

+Merge the data bit detection and data byte assembly into the same loop

+
+Also change the way phase correction works. the original code saves the

+and then restores aux[] back to m[] afterwards. Change this so that m[]

+Commit: b4805ea
+Two important fixes to CPR decoding: wrong cast and more precise timing.
+
+This commit address two issues with the implementation of CPR decoding:
+
+Fix #1: The two functions N() and DLon() used to have the latitude
+parameter as an integer (!), basically truncating the fractional part
+before calling the NL() function to perform the lookup.
+
+This resulted into random strange movements of aircrafts, especially
+jumps or shifted positions.
+
+Fix #2: Use milliseconds for CPR odd/even timestamps. Dump1090 already
+tried to use the most recent packet received among the odd and even
+packets currently available, however to do this correctly millisecond
+resolution should be used, otherwise many times the odd and even packet
+appear to have the same time in seconds and we don't always use the
+latest received.

+Commit: 69ae249
+New AP brute forcing algorithm.
+
+The old approach was to loop over a small circular buffer of recently
+seen addresses recomputing the CRC every time: this prevented the use of
+a big cache, and 20 entries was too small in case of high traffic and
+big range antennas.
+
+ at prog on ##rtlsdr suggested to use an alternative algorithm where
+instead we compute the CRC of the message, and xor it to obtain the
+address, that is later checked in our list of recently seen addresses.
+This is a lot better and allows for bigger tables in O(1) lookup time.
+
+I used this idea to implement a larger 1024 elements table. Instead of
+writing a proper hash table I used the fact we are just dealing with a
+cache, so I just hash the ICAO addess and overwrite the old entry at
+that idex with the address-timestamp pair, not caring about collisions.
+
+The bigger table makes a huge difference:
+In a test vector of 113 seconds recording with 76 simultaneous aircrafts
+the new algorithm detected around 10k more messages (!).

+
+Commit: b3945d1
+Use 16 bit for the magnitude vector to improve sensitivity.
+
+As @keenerd noted on ##rtlsdr, using an 8 bit magnitude vector is not
+enough in order to distinguish every different I/Q pair.
+
+With this commit a few more messages with good CRC are detected.
+
+antirez <antirez at gmail.com>
+
+
+Commit: 417cab5
+Improved message detection and --stats option.
+
+The demodulation algorithm now only skips the current message if the
+CRC is valid, this improves the amount of messages detected with good
+CRC by ~ 4% since sometimes we are just a few samples out of sync.
+
+This also improves the amount of messages that can be fixed.
+
+The --stats option was added in order to better evaluate how the
+algorithm performs on the same input after some change. So if you run
+the program with both --ifile and --stats no Mode S message is logged
+at all, but at the end of the processing the program shows you the
+amount of messages decoded with good, bad crc, bit corrections, valid
+preambles and so forth.

+README for dump1090
+===================
+
+ * ppup1090(1)
+
+It appears that ppup1090 depends on a binary object from COAA (the makers
+of the Planeplotter software) which does not have a license attached to it.
+This violates the Debian Free Software Guidelines (DFSG) and so it is not
+built or included with the package.
+
+If you wish to build ppup1090 for your system you can visit the author's
+GitHub page <https://github.com/MalcolmRobb/dump1090> which includes
+instructions for building that binary.
+
+ * dump1090(1)
+
+The internal web server has been largely disabled. To use the web
+interface see the notes in /usr/share/doc/dump1090/README.http.

+dump1090 HTTP interface
+=======================
+
+The stock dump1090 provides a HTTP interface that is served from the same
+network code that handles all the network communication into and out of the
+daemon. This feature has been disabled in the Debian build due to the
+complexity of auditing and maintaing the code. The web interface is still
+included and can be served by a HTTP daemon such as Apache2.
+
+A sample Apache2 configuration file suitable for modification is provided in
+/usr/share/doc/dump1090/examples.
+
+Most users can get the web interface running by:
+
+1) Install Apache2
+$ sudo apt-get install apache2
+
+2) Enable the proxy and proxy_http module:
+$ sudo a2enmod proxy_http
+
+3) Copy the sample configuration and modify as needed.
+$ sudo cp /usr/share/doc/dump1090/examples/apache2.conf \
+ /etc/apache2/conf.d/dump1090.conf
+$ sudoedit /etc/apache2/conf.d/dump1090.conf
+
+4) Restart Apache
+$ sudo invoke-rc.d apache2 restart
+
+5) Browse to your system at http://<your dump1090 host>/dump1090/

+.SH DIAGNOSTICS
+The Debug mode is a visual help to improve the detection algorithm or to
+understand why the program is not working for a given input.
+.PP
+In this mode messages are displayed in an ASCII-art style graphical
+representation, where the individual magnitude bars sampled at 2MHz are
+displayed.
+.PP
+An index shows the sample number, where 0 is the sample where the first Mode S
+peak was found. Some additional background noise is also added before the
+first peak to provide some context.
+.PP
+Select frames to log using the following flags:
+.TP
+.B
+d
+Log frames decoded with errors
+.TP
+.B
+D
+Log frames decoded with zero errors
+.TP
+.B
+c
+Log frames with bad CRC
+.TP
+.B
+C
+Log frames with good CRC
+.TP
+.B
+p
+Log frames with bad preamble
+.TP
+.B
+n
+Log network debugging info
+.TP
+.B
+j
+Log frames to frames.js, loadable by debug.html
+.SH EXAMPLES
+.TP
+The most basic usage is with no flags, which will open the first found rtl-sdr device and begin printing out hex dumps of the received packets.
+Most people will either run this in interactive mode or as a daemon.

+Description: Ensure socket fds are cleaned up after the connection is closed.
+.
+This affected HTTP connections which create a new conection every second for
+each browser-client; after a while no new network connections could be made
+to dump1090.
+.
+(Although not mentioned in the commit messages, it also fixes a bug which would
+segfault when accessing closed, deallocated send-sockets (modesSendAllClients)
+which were not written to, and then opening a read-socket (modesReadFromClient)
+the socket would be automatically freed by modesFreeClient, and then
+modesReadFromClients would try accessing the freed client struct, segfaulting
+the program. This was corrected by adding the modesCloseClient function, which
+closes the client connection and marks it as invalid, and clients are only
+actually freed later).

+Description: Disable local file serving from the internal HTTP server.
+ This patch relies somewhat on the 02-http-buffer.patch being applied.
+ .
+ This patch also adds support for user lattitude and longitude variables
+ on the command line to be passed up to the web ui, removing the need for
+ the user to edit both /etc/defaults/dump1090 AND config.js.
