THIS IS A SUMMARY PAGE.  FULL DETAILS ARE LOCATED IN THE SOURCE FILE.


INTRODUCTION:
=============

Sample Java Applet for use on BL2000.  You run the Applet in a web
browser on some client, and it communicates back to the BL2000/

	TESTED:	Dynamic C 7.05P
		Java 1.3.0_02 (downloaded from Sun, April 2001)
		Microsoft Internet Explorer 5.00
		Netscape Navigator 4.72

The Java "class" files are part of the sampel distribution.  It uses
two TCP ports, HTTP and a command port (DAC_SERVER_PORT in the code).
From your browser, both of these ports must be reachable.  Requires
listener classes from Java 1.1 runtime. Applet now ensures these
classes exist before it tries to use them!


COMPILE:
========

If you want to re-compile the Java source (not required), use the
simple MS-DOS batch file "m.bat" in the ./pages/ directory.  ("m" is
short for "make".)  Compile and download the C program.


DOCUMENTATION:
==============

If you want the class documentation, you need to run "javadoc".  Those
files are not part of the sample application, sorry.  From the batch
file type "m doc" to run javadoc.


RUNNING THE APPLET:
===================

Only one applet may connect at a time.  The "home page" of
the BL200 contains the applet.  It will present two horizontal pairs of labels and scrollbars.
Hook up a voltmeter the BL2000 a digital-to-analog output port (there
are two of them).

On the browser, slide either slider.  The voltage on that DAC (0 for
top scrollbar, 1 for bottom scrollbar) will vary proportionally.  When
you are done, either close the browser or leave the page.  That will
close the network connection.
