Many changes:



1) Queuing routine completely rewritten.  This controls most transmissions

of data, both RF and TCPIP.  Ctrl-Alt-Shift-Q will display the Queue, but

you will not be able to do much with it.  But it will show multiple ACKS

when they occur or when a Posit is transmitted from a station that has been

IGated.



2) ACKS - the program will generate multiple ACKS for messages received from

through multiple digipeater hops.  Note that the number of hops is

determined by the first packet heard for a given message.



3) IGated Acks - the program will transmit 2 Acks for all gated Acks, these

spaced 10 seconds apart.  This in hope to improve through put of message

Acks.  This is experimental, and may be removed later.



4) MAPS - A number of new maps have been created.  One is a dedicated

Digipeater Map.  And 4 "By Icon" maps are possible.  Also, 5 new Weather

only maps have been created.  The Wind Direction map will have map notes

with the "tail" pointing in the direction of the wind



5) MAP MOP Files - Map Options are now available for all map types.  All

maps will be drawn with the map NAME followed by a + and either A or B.

Example:  WindSpeed+A.SA5.  The MOP file associated with this map will be

WindSpeed.MOP.  If WindSpeed.MOP is not defined, then MapOptions.MOP will be

used.  It MapOptions.MOP is not defined, then the current values for the Map

Options will be used. Whew.  Map Options now include Map "Instance".  This

means which Instance of SA that a map will be directed to.  The default is 2

which means, NOT the one you might be zooming in on, but you can specify 1

if you wish.  The program now supports 4 instances.  This is artificially

limited.  More could be used, but this eats up more RAM, etc.  4 instances

for now.



6) Setup-Lists.  A new list has been created:  Gate Object based on object

Icon.  Also, the Gate Callsign function has a new "switch" to enable or

disable this function.



7) Trayicon is now in "native" code and does not require the OCX. An uninstall

batch file has been included to remove the v0.9.19 OCX.  Execute the batch 

file, Uninstall0919.bat.



8)  Messages and Objects can now be transmitted in NEW APRS message format.

This will be the default state, but in this state, old versions of APRS will

not decode the message or object



9) Messages - transmission of messages can now be either sequential or in

parallel.  In sequential, if a message gets "stuck", it will hold up all the

following messages.  This is added in concession to APRSdos which does

sequential message transmission.  I'd prefer to sort on receive, but need

more message info, this is why the message numbers are now 4 digit.



10) Coordinates.  The map datum of APRS is WGS84.  APRS+SA now supports

entry of coordinates in any of 122 map datums in degrees, degrees/minutes,

degrees/minutes/seconds, and now in UTM.  This applies to your current

position, Map Centers, and Objects.  Map Datums are recorded in Datum.TXT.

You can add more datum's as needed.  Be sure the parameters are correct.

Not all map datums have been tested.  I use the Defense Mapping Agency's

program MADTRAN as a benchmark for my Datum  and UTM transforms.  The 

Datum list is from the University of Texas.  There is also a new menu on

the Position, History and Object pages called Coordinates.  This can be

used to review a station's coordinates in a different Datum other then 

WGS84 and in UTM or Degrees, Degrees/Minutes, or Degrees/Minutes/Seconds.

Also from the coordinate window, you can locate the entered coordinate.

Note that if you change either the Lat/Long or UTM coordinates, click the

appropriate convert button to get the UTM or Lat/Long equivalents.



11)  APRServe Logon and Auto-Reconnect has been changed.  The program will

now do connects in the "back ground".  The keyboard remains active during

attempted connects to APRServe.  Also, if a connect fails, the program will

automatically go to the next server in the list.  Also, is connection gets

dropped, the next server in the list will be tried.  If the PPP connection

stays open, APRS+SA will try and try and try to keep the connection open.



Fixes:

1) No delayed ACK is now generated for Group Messages.
