	A few notes on GPxfer V2.2 ---
	
	If you are familiar with GPxfer V2.1 you will notice several
	changes in the monitor portion of the program.  The ability to
	display several more NMEA sentences has been added plus certain
	data can be sent to the printer by pressing the F3 key.
	Also, some bugs were removed from the program resulting from
	different NMEA versions.

	This program will upload waypoints to a GPS using waypoint numbers
	001 thru 500, it will not upload using names.  If the monitor
	program is displaying data where the downloaded waypoint is a name
	and not a three digit number it will display the first three 
	letters on one line and the waypoint name stored in the library
	directly beneath.  If a proprietary scheme is used to upload
	waypoints then you will have to use that manufacturer's software
	or a sharware program that is specific to that device.

	Program development was done mostly aboard a container ship using
	Trimble instruments.  But I also use it for my own personal and
	more modest GPS (Garmin 45).  Although modest in price it is an
	excellent receiver.  Of course I can only use the monitor section
	because Garmin uses proprietary GPS waypoint uploading.

	You can demonstrate the GPxfer program's waypoint/route uploading
	features before a GPS cable is made.  Simply connect a modem to 
	COM1 or COM2 so the program thinks you are connected to a GPS.
	The signal transmitted goes no further than your modem.
	This also allows you to view the monitor screen.  Although without
	signal detection movement, data, or cross track error tune bar.
	If you try to open a COM port that has a mouse attached, you will
	probably have to reload your mouse driver.  Otherwise, no harm done.
	

	The waypoint library supplied is not empty.  It consists of about
	65 waypoints used by a merchant ship in the U.S. West Coast/Asia
	trade.  All waypoints can be eaisly over written by zeros and the
	name deleted.
	
	Instead of uploading directly to a GPS you can copy to a file named
	gpx22.dat (waypoints or routes), this file is in the NMEA format.
	To do this press Alt+F after waypoint/route selection.  you could
	then upload this file using another computer that is not running
	GPxfer software by using a DOS batch file or command line, using
	MODE and TYPE commands, with the TYPE command redirected to the
	correct COM port.	
	For example...
				MODE COM1: 4800 N 8 1
				TYPE GPX22.DAT > COM1

	The GPS receiver has to be set up as described in the MANUAL 
	portion of this program.

	When uploading routes, you are actually just transmitting waypoint
	numbers.  So, make sure you have updated the GPS waypoint library
	to agree with the computer version.

	Hope some people in the maritime business, work or pleasure, have
	occasion to find this program useful.
