README.OUT       APRS NMEA-0183 OUTPUT for OTHER COMPUTERS

APRS can output NMEA-0183 position data to other computers via a 4800 baud
data link.  This option is useful if you have existing software that takes
NMEA-0183 position data (for a single unit) and you want to have the multi-
station capabilities of APRS.  In this arrangement, APRS serves as a front end
processor to handle all APRS reporting and communications with multiple
stations and vehicles, while sending selected position reports over to another
computer running other Geo-location software.  This very powerful feature is
only available in the commercial version of APRS currently distributed by
PACCOMM.

Since many other Geo-location software packages accept NMEA-0183 data from
GPS and LORAN devices, APRS will simulate a GGA/VTG data format as if it
was comming from a navigation device.  To select an object or station for
output from APRS to the other computer, simply use the cursor to HOOK the
station.  Each time you hook a station, a NMEA-0183 report will be sent to
the other computer via the selected COMMport (usually 2 if your TNC is on
COM1).  If you want to track a particular station continuously, simply hook
the station on the P-List and select TRACK function.  Then, every position
report from that station will generate a NMEA report to the other computer.
Also the +/- keys can be used to quickly step through every station in APRS
and transfer those posits over to the other computer.

This pre-processor arrangement allows APRS to keep the big picture of where
everyone is on the big maps, and allows the normal APRS communications
capabilities between stations.  All detail maping functions and database
applications are then run on a companion computer indpendent of APRS.  The
communications operator simply hands off position reports to the database
operator whenever further detail on a unit is needed.
