GARCOM12 - Reads and displays NMEA sentences and reads and 
	stores Garmin Tracks, Routes, Waypoints and the Almanac.

1.  Added more fonts and activated GRMN/GRMN->[Routes, Waypoint,
	Almanac]->Upload.  6/24/2000
2.  Added an "Auto File" feature that will calculate a file name
	for uploads instead of requesting a name. 6/27/2000

PROGRAM OVERVIEW:

GARCOMM is a single threaded OS/2 PM program that will read data
from a serial port (1 - 4 configurable) and display it on the screen.  The
data must be in standard NMEA sentences.  The user must configure
the communications parameters before attempting to read the port.
Configuration data is saved over re-executions.

GARCOMM will also communcate with a GARMIN GPS using the 
proprietary Garmin protocol.  It will allow uploading of the track, route
waypoint and allmanac data saved in the GPS and store it in a .trk, .rte,
.wpt and .alm files respectively  The .trk track file is in the proper format
for use by Movemap in simulation mode.

SETUP:

Unzip the program in the mapprog directory on the same hard drive 
that contains Movemap and the map directories.  GARCOMM uses
Borland controls; so if you haven't added bpmcc.dll to the \OS2\DLL
directory you must do that.  It also displays a picture of your choice
that must be named booktitl.bmp and must be in the mapprog directory.

The bundle contains GARCOMM,exe, this readme file and bmcc.dll.

OPERATION:

You can execute the GARCOMM from an OS/2 prompt or a icon.  The
first time the PM session comes up you must:

File->Config Comm  will open a dialog box that will allow you to 
	select Comm Port, Port Speed, Data Bits, Stop Bits, Parity
	and Comm Format.  The values entered except for Comm
	Format are saved over executions of GARCOMM,
File->Exit will allow a graceful exit from GARCOMM.

Data Mode->Start opens the serial port using the current Comm
	parameters and begins reading the input.  When (if) it
	detects the first good NMEA sentence it will black the
	screen and begin displaying sentences scrolling from
	the bottom and off the top of the screen.  If the opening
	screen does not erase it likely means either that you
	misconfigured the communications parameters or your
	GPS is not transmitting correctly.
Data Mode->Reset closes the comm port and stops receiving
	data.  The screen will be left with the most current set of
	NMEA sentences displayed.
GRMN/GRMN->Tracks->Upload enables the loading of saved
	tracks from the Garmin GPS using the GRMN/GRMN
	protocol.  A dialog will open asking for a fully qualified
	file name in which to store the uploaded info.  Once
	this is entered GARCOMM will read the port looking
	for the initial Garmin sentence.  GARCOMM's bit rate
	must be modified to match the GRMN/GRMN transmit
	speed in order for this to work.  After selecting this
	option the Garmin GPS can then be put in track 
	upload mode and GARCOMM will receive the track data
	and store it in the designated file.  The track data will
	be displayed as it is received.  When complete GARCOMM
	will display some statistics and error info.
GRMN/GRMN->Tracks->Reset disables the uploading of GRMN/GRMN
	track data.

GRMN/GRMN->[Route, Waypoint, Almanac]->Upload work the same
	way as GRMN/GRMN->Tracks->Upload except they default
	to different file types [.rte, .wpt, .alm] for data storage.

GRMN/GRMN->[Route, Waypoint, Almanac]->Reset disables the 
	uploading of [Route, Waypoint, Almanac] data.

GRMN/GRMN-->[Route, Waypoint, Almanac]->Download is not
	operational yet.
