Re: [Xastir] Correct command?

[Alex Carver]

The backslashes allow that command to be split across multiple lines.  If you 
want to use only one line, don't use the backslashes.

Just copy it as a three line command.  Copy and paste the first line including 
the backslash (\) on the end, then hit enter.  Repeat for each line.  And, yes, 
the > should be in there.

Re: [Xastir] geo files for simple maps

[Alex Carver]

It's just a simple .geo like the others you've seen.

First line is the keyword FILENAME and then the filename of the image
Next line is keyword TIEPOINT followed by the pixel x, pixel y, longitude, and 
latitude of the pixel
Final line is another TIEPOINT for the opposite corner in the same format.

The overlay of "S" is supposed to stand for "Tropical Storm".  The overlay will 
change to any of the digits 1-5 if the storm becomes a hurricane and the 
overlay digit is the category of the hurricane.  So Ike currently should have 
an overlay of 4 since it's spun up to a Category 4 hurricane (not so good for 
my parents if it continues on its track).

[Xastir] dbfawk, overlapping lines, and more

[Alex Carver]

I was playing around with the latest offering from the National Hurricane 
Center website which is a bundle of GIS files including shape files for the 
three- and five-day projection cones of the various storms.  To that end, I was 
tinkering with a small dbfawk file for these shape files and sort of have 
things working but with a few cosmetic issues I'd like to resolve (and somehow 
can't).

First, is there a way to resolve or reorder overlapping lines?  The five-day 
cone has polygon data for the three-day cone already inside it.  The problem is 
that the five-day cone ends up being drawn over the top of the three-day cone 
so I can't see any of the three-day lines except for the very last arc of the 
cone.  This is only cosmetic since the three- and five-day cones overlap 
completely but I was trying to get a red cone for the three-day and a yellow 
one for the leftover bits in the five-day.

Second, if two DBF files have the same fingerprint, is there a way to 
distinguish between the files assuming that the file name is not known in 
advance?  The reason for this question is the hurricane track is provided as a 
separate file from the cone polygons and I was trying to display it in a 
different color.  But, the track and polygon files have identical DBF column 
names.

Third, is there a way to kick Xastir and force it to reindex the maps and 
refresh the screen non-interactively?  If I get this working, a cron is going 
to download the track, drop it in the maps directory and it should be able to 
signal Xastir to reindex the maps and refresh the display so that the track is 
updated.

You can download the whole set of Tiger data but it'll be a touch slow.  They

I bet there's a serial getty sitting on the port right now for a serial 
console.  Look inside a file called /etc/inittab for the serial port.  You can 
do it this way:

grep ttyS0 /etc/inittab

If it comes back with a line that doesn't have a # in front, that's probably 
part of the problem.

If you want vector, why not have Splat output its L-R path-loss contour data 
into a text file and then do some scripting on that file to generate your 
contour of interest.  Make the cutoff some dB, plot only up to that dB of loss, 
then strip out all points nearest that dB in the contour file.  Use the points 
to generate the multi-line packet showing the region of maximum acceptable loss.

This either means the file doesn't exist or the permissions are such that

Actually this has nothing to do with the radar images you serve up.  I only 
pull one radar image directly from NWS servers.  So it's the NWS feed that

I'll give it a shot.  It's currently using IM which means a lot of fun trying

Well, I figured that part. ;)  I meant if there were any ideas why the system 
is leaking in the first place.  The Xastir process is the one consuming the 
memory.  There aren't any IM/GM processes running when Xastir is locked up.  In 
fact, only Xastir is the one locked up since the desktop still works fine.

[Xastir] Xastir and maps lockup - found part of problem

[Alex Carver]

Ok, running the very latest that was available in CVS, my copy locked up after 
a few days of running with the NWS gif map of my local radar.

So I poked around and apparently what happened was that Xastir used up all the 
free RAM in the system.  Killing off the process releases almost 30 MB of  RAM. 
 The system has 512 MB total, with Xastir freshly restarted there's 28 MB free. 
 Swap is 512 MB as well but most of it was free while Xastir was stuck.

Top showed Xastir as the largest memory footprint in the system when it got 
stuck.  Barely any CPU was being used but quite a bit of RAM.

Any ideas why the memory consumption would keep creeping up with the GIF raster 
map?  The only other map is a Tiger but I've run one of the tilers on the Tiger 
maps so the maps are quite small and I'm zoomed in to 256 (two full states and 
a few pieces of neighboring states).  The Tiger files currently loaded are 
state borders and county lines.

[Xastir] Inverted video in dialogs not functional

I just installed the latest code from CVS and noticed that none of the dialogs

The regular text is there but when an item is selected, the black bar shows up 
but the text color stays black instead of changing to white like it used to do.

I'm trying a recompile to see if I can solve my map problem.  Xastir had been 
running for two weeks straight now with no problems as long as my radar map was 
disabled.  It would only run for one day before freezing if I left a radar map 
selected.

It's about as sane as it can be until Bob B. changes his mind again which

In theory it's meant to be machine parsable so that the new D710's can read it

Ok, it takes about a day and a half for the system to lock up under Fluxbox.  
Checking with ps ax, there is no instance of an ImageMagick process running in 
the background.  Top shows Xastir is consuming 95% of the CPU but not much RAM. 
 There are no error messages in the console about a failed download for the GIF 
image this time.  It just quietly died.

I'll check these as soon as I can.  ImageMagick isn't running according to top 
when the lockup happens.  Unfortunately it's not a few minute lockup.  Under 
Gnome it took at least a day or two to lock up.  Under Fluxbox it takes several 
days.  In both cases it's happening only with an NWS radar map (the only maps 
loaded other than the Tiger shapefiles).  For a while, everything works as 
expected.  The radar map (a single radar since I'm zoomed into one state for 
the most part) downloads and displays fine.  Then one day I'll walk by the 
machine and notice nothing is updating.  The last message left in the status 
bar is always referring to the NWS map when I see it locked up.  Prior to this 
everything (except a malfunctioning mouse) was working just fine.  So the 
system is completely junk free and up to date as far as I can tell.  Xastir was 
compiled from CVS.

I should also point out in addition to swapping methods that under Fluxbox the 
lockup period is longer than under Gnome.

[Xastir] Lockups using maps again

[Alex Carver]

Well I was wrong, even using Fluxbox the system locked up again while 
attempting to download the radar image.  It seems to have timed out on the 
download and then froze at that point, unable to recover.

The only maps I had going were the Tiger shapefiles.  However, I've since 
switched to Fluxbox from Gnome (which was the default on the installation) and 
everything is fine.  So there was something going on in the background with one 
of the multitude of applications that Gnome installs that likely caused the 
problem.  It's been nearly flawless with Fluxbox.

I have no idea what the problem is either.  I've never had this problem at all 
on any system.  Before I reloaded the machine, the only problem was the mouse 
not working.  Everything else was fine.

Re: [Xastir] Lockups on a fresh system

Ok, wget doesn't work either.  There was an error in the console that said that 
the radar image couldn't be downloaded, increase internet map timeout.  
However, the timeout is maxed out at 300s.  So apparently Xastir doesn't like 
it when a map isn't available but, in my case, it simply dies waiting for it.

Suggestions?

Re: [Xastir] Lockups on a fresh system

[Alex Carver]

Well, I've removed the curl libraries (oddly enough changing permissions on the 
include headers didn't break configure) and let Xastir pick up on wget and so 
far no lockups.

The system was using libcurl3 when I installed Xastir the first time.  
Fortunately nothing else requires curl or I'd be stuck trying to figure out a 
way to force Xastir to accept wget instead of curl.

I'll see how it does over the next few days.  Then I'll enabled the bulletins 
again and see if that blows anything up.

Is there a way to force the use of wget without recompiling?  I compiled using

Ok, it locked up again while handling the radar GIFs.  That was the last thing 
Xastir seems to be doing as it's the message that was at the bottom in the 
status bar when it froze.  No bulletin box was up this time, it just froze on 
its own.  It had downloaded the map just fine when I started Xastir.

I guess next thing to try is a different window manager.

I look forward to seeing what happens with your bulletins turned on.

As for Tif, I'm using lesstif on this system and, as far as I can tell, 
nothing's wrong.  The typical missing slider labels symptom of a broken Tif 
package is not present.  I see the labels just fine.

I'm only using Gnome right now since that's what installed.  The fresh install 
is because the mouse was completely dead and nothing I tried would fix it.

It's a fresh install of Debian Etch using kernel image 2.6.18-6 and the current 
WM is Gnome version 2.14.3.6.  The system is mostly stock right off the install 
CD and the online repositories.  I've only removed applications that aren't 
needed on the machine which installed by default (games, OpenOffice, etc.).  
Xastir was compiled from source obtained via CVS.

Everything else functions normally.  The WM doesn't stop running and I can 
manipulate other applications as if nothing's happening.  Xastir is just simply 
stuck doing something.

Re: [Xastir] Lockups on a fresh system

[Alex Carver]

Ok, no lockups when I disabled the map so I reenabled the map on Friday.  It 
ran just fine all weekend long...until today.

Top says Xastir is using 100% CPU and the last thing it was about to do is 
refresh the maps.  There is no ImageMagick process running in the background.  
However, there is a bulletin window up (it opened on receipt of two bulletins) 
but I can't close the window (though I can move it) and I can't do anything 
with the Xastir main window.

This is the same condition I've seen before.  The maps were going to (or in 
process of) refreshing but a bulletin window was up.  I'll have to try to 
disable the bulletin window (I forget where) and see what happens there.

More thoughts?

Could do that, I'll try it next time I notice the window has locked up.  The 
mouse never stops working, only the Xastir window contents are frozen and not 
refreshing.  I can still move the window around the screen and use the rest of 
the machine normally.  But anything I want to do with Xastir is just frozen.  
If I try to click on something inside the window (like the menus), nothing.

Yeah, it's not running anymore but there were quite a few other things acting 
up so it was just easier to wipe the machine and start from scratch.

I have my DNS servers programmed in there and the package manager doesn't 
complain a bit about failing to resolve anything.  I'll turn off the radar map 
and see what happens.  The only remote maps I have are two radar maps with zoom 
levels set so only one or the other shows up.  Both are now off for now.

[Xastir] Lockups on a fresh system

[Alex Carver]

My mouse wasn't working correctly on my AMD K6 Xastir system so I decided to 
flush the whole thing and reload Debian Etch on there (which is what was there 
before but gpm was being weird).  The only thing I kept from the old system 
were all my maps and customized config files.  The rest is new.

I'm noticing, however, that Xastir is locking up after a period of time and it 
seems to be doing it during a map reload.  Specifically it's locking up when I 
download a radar image from the NWS.  Works fine for a while and then it just 
stops responding.

Fresh install of Xastir compiled from CVS.  I get a 'yes' on everything but the 
last two modules (Festival and GPSMan are not installed, don't need them).  The 
rest of the system responds just fine.  The desktop is Gnome and it's still 
working, I can open new windows, drag things around, even open a terminal and 
kill Xastir.  Then I can restart it and everything is fine for a while and then 
back to the lockup.

Ideas?  Needed info that I forgot?

Re: [Xastir] digipeater coverage plots

[Alex Carver]

Not quite the implementation you're talking about but what about using Splat 
(http://www.qsl.net/kd2bd/splat.html)?  It can generate a line-of-sight 
coverage map for you very easily.  You could start with the base station, find 
the gaps in coverage, then deploy your fill-in digipeaters in those gaps.


Splat uses data from a Space Shuttle topography mission to get terrain data for 
the predictions.  It'll also use information about the soil conditions to 
adjust propagation.

Re: [Xastir] bluetooth serial port issues

[Alex Carver]

If the software is written natively for OS X (rather than just a Unix compile) 
it might be more aware of the hardware system and gracefully handle hardware 
errors including the disappearance of hardware.  That's why I was suggesting an 
actual OS X application and not necessarily another Unix/Linux program.

You're not going to be able to MUX the devices easily if they speak only RS232. 
 Each one will need an address.  What you're talking about is trying to convert 
nearly every device to RS485 but there will have to be much additional hardware 
at each link node to ensure that data passes around properly.  There are 
Bluetooth based RS485 systems (multi-drop) that would be a start for you but 
none of them are going to be in your budget.  I believe one node is around 
$120.  On top of that, you'll have to put in a microprocessor at each node in 
order to repackage the data stream and insert an address into the data header.  
I've seen a couple standalone converters that will let you attach an address to 
an RS232 device but, again, more money.  You'll also have to do lots of 
manipulation at the computer end to translate the data in and out of the 
virtual serial ports while tagging everything in and out of the real port with 
addresses so that the data is routed
 properly.

My suggestion would be to try and isolate Xastir from the serial port.  Get 
something like a serial port replicator software package that can create 
virtual ports and connect them to real ports (I know there's GPSGate for 
windows but I don't know if there's one for OS X).  Then just have one virtual 
port connected to the one real port.  Have Xastir connect to the virtual port 
which will always exist.  If the real serial port vanishes, the replicator 
software should be able to survive.

This is true though a script allows other prep work to be added (permissions 
for serial port for example) if needed.  But indeed shell aliases work, too.

Yes, -c /path/to/config/directory

So under one account have three configuration directories:

Then start xastir accordingly even using shell scripts:

xastir -c ~/bob/.xastir.night

~/xastir.day:
#!/bin/bash
xastir -c ~/bob/.xastir.day

My copy uses no TNC (for now) and a filtered
connection to rotate.  It's also using Tiger maps
(though I rarely pan it anywhere) and it downloads one
radar GIF every ten minutes or so directly from NOAA.

Top shows:
  VIRT  RES  SHR S %CPU %MEMTIME+  COMMAND
 
34796  10m 4276 R 16.6  2.3 156:42.48 xastir

This is running on an Athlon K6 with 512 MB RAM
(though some of it is used for on-board video).  Only
problem I'm having right now is the mouse not working
but that's not Xastir's fault.

It's different.  Xastir can, for any US user, show
things like NWS watch and warning boxes, radar images,
and whatever else you can fit on your map that Google
Earth will not.

Plus, for me, I don't feel like letting Google put

A variety of reasons.  You can have Xastir running
somewhere and let people see a map with a browser
instead of a full implementation of Xastir.  Or you
can have several people looking at the map and only
once instance of Xastir running.

Yes, it's in the timings configuration panel at the

Re: [Xastir] Xastir web interface?

Regarding your cron entry not working, I find it's
usually safest to write a script into a file (even if
it's a one-liner) and then only call the script from
cron.  It tends to be much happier.  So one extra file
is needed as follows:

~/scripts/convertimage.sh:
#!/bin/bash
#bash happens to be my preferred shell

/usr/bin/convert path/to/xpm path/to/gif


chmod a+x ~/scripts/convertimage.sh

What he was looking for was a way to make the radar
image translucent inside Xastir so that any other
layers inside Xastir would show through the colored
areas of the radar image.  However, since Xastir
doesn't support alpha blending at the moment, this
can't be done.  I don't believe the image code in
Xastir would even honor any alpha channel data in a
GIF either.

Just another tick mark for Xastir 2, right? :)

So you must be wanting to make all the data sort of
translucent as if it were a sheet of colored plastic,
right?  I don't think you're going to be able to
accomplish that without doing a major rewrite of Xastir.

Ooops, guess not anymore.  The batch I have happens to
have FTDI chips in them but it seems that the OEM
(which is actually ATEN) has gone to the Prolific
chips.  On the other hand, ATEN has the drivers
available on their website including source code for Linux.

The serial adapter from IOGear is based on the FTDI

I see one sticky wicket for that in the consumer
equipment (now that I got to see the data format). 
Some of the units send unsigned integers for certain
values in their serial data stream.  They're also
using fixed width fields in the data stream.

For example, if the wind vane broke or didn't exist,
what value do you send for wind direction?  The
Ultimeter uses 0-F to send 16 directions of wind.  The
wind speed is encoded in two hex digits (no mention of
signed or unsigned here, though) so what do you send
there?  A report of 00 is valid as is 8A (140MPH not
often, but it might be valid in a hurricane).

If it's perhaps a simple firmware change that can be
installed in all existing units, maybe the no sensor
value should be an overrange.  Wind speed sensor
missing would be FF (unless there are 255 MPH winds
somewhere).

It looks like the temperature sensors might be get
away with a negative underrange, though, since they
have to transmit negative temperatures.  I can't tell
how they do it, though (whether signed integers or
some offset).

The program socat works pretty well for remote serial
over network connections.  The only sticky wicket I've
come across with it is the apparent inability to set
serial port speeds on the server side (where the
physical port is actually located).  Openwrt should be
able to fix that with regular ioctl() calls through
something like setserial.  Socat is supposed to be
able to do this, but on my systems it doesn't work.  I
have to use something else to set the port up first
then let socat latch onto the port.  After that it
works just fine.

Crazily enough, I have Xastir running on a Debian
machine in my living room sucking data from a TNC in
my office connected to a WinXP machine.  Socat sits
quietly in the background running on a minimized
Cygwin terminal.

Oh noes, replying to myself, bad Internet form!

Thought to those that code better than I (I only deal
with text, hehe):

I see that, quite smartly, the station list dialog is
rather generic and the data used to populate it is
determined by the menu choice.  What about generating
a window with a different handle (so that other
station lists could be brought up separately) and then
the station list is populated by comparing stations to
a user's 'budlist' of sorts as a new flag condition? 
Then a person could build up a bud list (whether by
GUI or by text file) and the stations would be on the
list.

Of course this would probably mean some kind of
callback in the station list dialog that could
actually bring up the station info dialog when the
station is clicked.  Or maybe it would be sufficient
to leave the current operation of centering on the map
and then bring up the station info via the context
menu as per usual.

I'd like to see an example of UI-View decoding
telemetry.  It sounds interesting.  As for the
stations, I can see in the code that it's set up for
only one window, destroying and recreating the window
as each new station is brought up.  I'm sure that

Under a Unix environment, you can sometimes pull some
very clever trickery to accomplish this.  In one case
that I've tried (though not entirely successfully as
I've still got some details to work out), using a
combination of socat and tee I was able to read (but
not write) data from a serial port and distribute it
to a couple other locations.  The closest thing I've
seen to distributing a serial port to multiple
computers was a program called ser2net but it seems
development has stalled on that.

Unless TCPCOM is using something proprietary on the
network connection, you can use socat on the Unix side
of things to make the transition from network socket
to virtual serial port (since it should be pointed out
that TCPCOM is a Windows program and won't work on a
Unix/Linux system).

I'm probably going to sit down one day this year and
see if I can come up with a program equivalent to
TCPCOM/GPSGate/etc. for a Unix/Linux system.  The main
thing it has to do is just coordinate data transfer
between systems.  Since one typically wants only one
system to ever have the ability to talk to a serial
device (as opposed to listening to it), I was thinking
of having an out-of-band signal (control port) that
would allow a connected machine to take command of the
serial device.  Any other connections would be listen only.

There is a weather station list in the View menu and a
mobile station list.  It currently doesn't filter for
a specific transmitter type or show the raw data
(though the weather list does show weather data for
all stations).  Of course you can always add code to
create a new window that runs through the list and
brings up only specific data.

Right click a station and choose Station Info to see
the data sent.  It will pretty print a lot of data so
the raw packet isn't visible in this window but the
data is there.

Steve can fill in a lot of the details but he's trying
to use two computers with one Ultimeter and doesn't
want to split the serial ports in hardware, instead
he's going to try splitting the port by software.

I took a peek in Xastir to see how it supported
weather stations and I see it will either support a
serial port or a network port.  Still don't know the
format but I'll need to poke around to figure that
out.

Not supporting the 'wxnow.txt' file I think is
reasonable.  The idea is that Xastir can do a lot of
things on its own without depending too much on
external programs (though it's certainly extensible in
some respects).  Having Xastir directly handle reading
from the weather station ensures that some problems
are avoided such as reading a file that's being
written at the same time.  It also allows for the
display of the data as it's acquired instead of
waiting for the file to update.

According to the help file, it currently supports a
Radio Shack type weather station and a specific format
of ASCII as output (presumably by a Peet Brothers
weather station).  I don't know what the Ultimeter
puts out for data over the serial port nor do I know
the specifics of the two formats that Xastir
understands.  I imagine there may be a way to get the
Ultimeter to work in Xastir with some code changes or
data massaging.

I'm not sure how Xastir handles weather data, so I'll
leave that to someone else to answer (though I'm
curious for the eventual time when I can actually put
up a weather station).

If Xastir wants a serial port instead of a file to
read from, then you have a couple ways of sharing the
port.  The easiest way is obviously the second serial
dongle if you're intending to keep two completely
different machines.

The harder way that doesn't require an additional
adapter is to use a few bits of software to create
virtual serial ports with the possibility of
connecting them over the network.

This second method depends on the configuration.  If
you can move your weather web page over to the Mac,
you can compile and run everything under OS X.  If you
don't move it, you'll have to find software to work on
both the Mac (compiled or otherwise) and on the
Windows machine.

Leaving the server on the Windows machine:  The
Windows machine would have to create two virtual ports
and share one over the network.  The Mac would create
a virtual serial port via a network connection to the
Windows machine.  There's software for splitting up
ports on Windows and making them available over
network connections but I don't know how well they
work.  Some of them are commercial so you'll be
paying.  I think one that's rather popular is Franson
GPSGate.  The Mac only has to run a program called
'socat' which can turn a network connection into a
virtual serial port.

Moving the server to the Mac:  The Mac would be
running three small programs.  One would be 'ser2net'
http://sourceforge.net/projects/ser2net/ which can
create a network connection to a serial port but
allows multiple connections to that network port (as I
understand it).  Then the Mac runs two copies of socat
to create two virtual serial ports.

You mean the multi-color bars in the corner?  Those
indicate the status of each interface managed by the
interface control and which way traffic is flowing.

Check in the source code directory under the help
subdirectory and you'll find a help-English.dat file
and there's a short paragraph about it in there:

QUOTE
The last area will display the device status for each
interface. Each will display in order first to last or
0 to 9. The interface status is separated into three
areas, top device type, center data flow, and bottom
interface operational status.

The device type will show what interfaces are
configured. The color will show what type of device
the interface is configured for. Blues are for the
various TNC devices; Greens will show the GPS devices;
Yellow for Internet Servers; Orange for WX interfaces.

The center will show data flow in (arrow pointing
left) or data flow out (arrow pointing right) for that
interface.

A green box at the bottom will show if that interface
is active. A red box will show if the interface is
active but in an error condition. Otherwise nothing
will show if the interface is not active. 
END QUOTE

I just uploaded a single file that contains every
state and US territory.  I'm not exactly sure how
complete it is but it has over 180,000 cities and
towns listed.  A quick scan showed populations as low
as 60 in some cases.

Don't know Gerry's email address off hand to notify
him, but it's in the incoming directory as
0pop_places.gnis and the file can be exploded by state
using some basic shell scripting.  If anyone wants me
to explode it, I'll be happy to do so, I just figured
I'd dump the whole file there first as a backup.

Actually, it's sometimes handy to reconfigure the TNC
for non-KISS operation (a digipeater, for example,
that you shouldn't depend on the computer in case it
crashes), or diagnostics while inside Xastir.  I run a
TNC in command mode with Xastir precisely for the
digipeating of the TNC without the computer just in
case the machine dumps out due to something weird (and
I've got a weird system, two computers, one runs
Xastir and one runs the TNC).  I know I've wanted to
be able to send a command or two to the TNC before.

It's hard to see some of the arrowheads especially on
the vectors that have small magnitudes.  It seems the
arrowheads scale with the magnitude of the vector,
too, and not just the length of the vector line. 
Perhaps fixed sized arrowheads and color for the
magnitude like radar data?

Re: [Xastir] Compile issues

[Alex Carver]

Using a 2.4 kernel isn't exactly going to prevent use
of Xastir.  What matters is that the libraries are as
up to date as possible.  Is there any particular
reason why you don't want to upgrade the system to
etch and/or install a 2.6 kernel (not as critical) on
there?

I'm running etch on a lot of machines including an old
486DX4 with barely enough RAM to make it go.  It won't
hurt, I promise. :)  But, I didn't mean to include the
"etch" in that line.  My system is etch and I only
replaced "etch" on the first line with "woody" and
forgot to do it on the second line.  You may still
want to consider an upgrade from within woody, though.
 "apt-get -s upgrade" will do a simulation and tell
you how many things are out of date.

In regards to lesstif, I'd go ahead and try that.  I
had problems trying to get OpenMotif working on any of
my systems and just gave up and went with lesstif. 
Fewer headaches that way.

As to ImageMagick, yes you can absolutely download and
install from source.  There is a make command after
installing that will install the headers.  I'd have to
dig around to see what it was but I think it was "make
install_libs" or something similar.  By default it
won't install the libraries and headers when you
install the binaries.  But my current Xastir system
does use a version of ImageMagick installed from
source as did my Cygwin installation.

Re: [Xastir] Compile issues

[Alex Carver]

There's no "Universe" repository for Debian under apt
but you do need to check that your repositories are at
least set for "main", "contrib", and "non-free".

These two config lines should get you just about
everything in stable form:

deb http://ftp.debian.org/debian/ woody main contrib
non-free
deb http://security.debian.org/debian/ etch main
contrib non-free

Can you post some of the dependency errors?  I'm
suspecting that your system is in need of an upgrade
(which apt can do for you, too) because apt is usually
very good about resolving dependencies _unless_
installing a dependency will break something critical
in which case it stands aside and lets you try to fix
the problem.

Nice work on the latter part fixing the wind direction
(I'm not a developer but it's certainly a good catch).
 It might be that the code was borrowed from an older
version of the Peet protocol and no one noticed.

As for array of bytes/strings, in C there isn't really
a string.  It's an array of characters that have
loosely been called a string.  So data[2] is a single
character and will return only one character.  Data+2
is actually an address, not a character.  That's why
it's used in the substr() function: substr() is asking
for an array of characters, a start address and a
length.

To do what substr() is doing by using arrays, you'd
have to create an array of characters four bytes long
and then copy the data in like this:

char temp_data1[4]; /* array of char four bytes long
*/

temp_data1[0] = data[2];
temp_data1[1] = data[3];
temp_data1[2] = data[4];
temp_data1[3] = data[5];

Not as pleasant as just:

substr(temp_data1,(char *)data+2,4)

Also, the (char *) bit ensures that the value returned
by "data+2" is cast as a pointer (specifically to a
character).  Mainly you just want to be sure you're
getting a pointer to a memory location which is what
substr wants.

Interesting.  Well, I guess it's one of three things:
1. SC is flatter than I thought
2. This guy has a ridiculously tall tower (or tower
spot)
3. He's being quite generous with UHF propagation. 
The repeater in Atlanta at 1000 feet doesn't even
reach the Alabama line at 146 MHz.

Quite interesting anyway.  I guess it could be useful
for this application but wouldn't a PHG circle be easier?

The load is already there.  The servers are comparing
all the packets looking for duplicates and then
discarding the duplicates.  So the load on the network
shouldn't go up at all.  Rather you'd simply be making
visible a portion of the traffic that is otherwise hidden.

In that same train of thought, it would be nice if the
APRS-IS could show the duplicate packets instead of
discarding them.  Then you possibly _could_ get a
better understanding of the RF network by watching how
a packet propagates and duplicates itself.

I doubt it's Xastir because Xastir doesn't really know
it's a USB device.  As far as it knows, it's just a
serial port so it's likely the device itself or its
drivers.  You may want to try an adapter made by
someone else.  Several manufacturers use a chipset
from FTDI (Keyspan does not last I knew) and
apparently the FTDI chipset is well supported in many
OSes.  Even some Windows people have issues with Keyspans.

Yep, Motif/Lesstif is one that bombs out immediately. 
I just tried to recompile after removing Lesstif

If you selected Xastir in the software list that the
Cygwin installer presents, then it's downloading a
binary version, no compiling goes on.

It may be that you have a broken dependency that
wasn't resolved correctly by the installer.  Best
thing to do is as was suggested and download the
source code then follow the instructions for
installing Xastir from source.  It's not quite as easy
as point and click, but in the end it works better. 
Just follow the documentation online for the
installation and you should be up and running quickly.

As for GraphicsMagic, while it's the way to go
eventually, start off easier with the ImageMagic
libraries that are provided in the Cygwin installer. 
For an initial test, they work fine for getting Xastir
up and running on Cygwin initially.  My Cygwin install
uses ImageMagic from the installer.

Hmm, try this instead.  Open a Cygwin bash shell
(don't use the batch file directly from windows. 
Then, inside that, do 'startx' (no quotes) and you
should be presented with an xterm.  After that, in the
xterm, run 'xastir' and see what happens.

Is Xastir compiled from source or did you download the
prepackaged binary from the Cygwin sources?

run 'echo $PATH' (no quotes) from your command prompt
and copy the output here.  It may be that
/usr/local/bin is not in your path at all.

If it's not, do:

PATH=$PATH:/usr/local/bin ; hash -r

and then

which xastir

It should come back and say /usr/local/lib/xastir.

'DIR' (all caps) won't work at all.  'dir' may work if
the aliases got installed right (or the 'dir' package

Is there a function that can return currently owned
objects?  If not, is there an array or linked list
somewhere that contains the objects in some way (this
I assume exists otherwise Xastir would never remember
its objects).
