<h2>
<a NAME="Introduction"></a><font face="Arial, Helvetica, sans-serif">Introduction</font></h2>
<font face="Arial, Helvetica, sans-serif">RFax is a Java[TM] component that can
send faxes to any group 3 fax machine.</font>
<p><font face="Arial, Helvetica, sans-serif">RFax requires:</font>
<ul>
<li> <font face="Arial, Helvetica, sans-serif"><b>fax modem class 1, class 2
or class 2.0</b>. This must be an analog modem (no ISDN).</font></li>
<li> <font face="Arial, Helvetica, sans-serif"><a href="http://java.sun.com/products/javacomm/index.html">Java[TM]
Communications API</a>. This package allows RFax to access the serial ports
on your computer.<br>
<br>
</font><font face="Arial, Helvetica, sans-serif" size="-1">Note: Java Communications
API 3.0 is not yet available for windows so you must use the Java Communications
API 2.0. Let us know if you cannot find it.</font><font face="Arial, Helvetica, sans-serif" size="-1"><br>

<li> <font face="Arial, Helvetica, sans-serif">Java[TM] Development Kit 1.1
or later.</font></li>

<h2>
<a NAME="evaluation"></a><font face="Arial, Helvetica, sans-serif">About
the evaluation version</font></h2>
<font face="Arial, Helvetica, sans-serif">The evaluation version will always
insert a watermark on the top of your fax pages.</font>
<h2>
<a NAME="installation"></a><font face="Arial, Helvetica, sans-serif">Installation</font></h2>
<font face="Arial, Helvetica, sans-serif">Installation of RFax is made
of 2 steps:</font>
<ul>
<li> <font face="Arial, Helvetica, sans-serif">Installation or Java Communications
API. Click <a href="http://java.sun.com/products/javacomm/index.html">here</a>
to download it. You must download the communications API and follow the directions
in the file <i>PlatformSpecific.html</i>. For exampe, if you are running the
Java platform on windows you must:</font></li>
<ul>
<li>
<font face="Arial, Helvetica, sans-serif">copy w<i>in32com.dll</i> to your
<i>jdkdirectoy\bin</i></font></li>
<li>
<font face="Arial, Helvetica, sans-serif">copy <i>comm.jar</i> to your<i>
jdkdirectoy\lib. </i>Include comm.jar in your CLASSPATH.</font></li>
<li>
<font face="Arial, Helvetica, sans-serif">copy <i>javax.comm.properties</i>
to your<i> jdkdirectoy\lib</i></font></li>
</ul>
<li>
<font face="Arial, Helvetica, sans-serif">Installation of RFax:</font></li>
<ul>
<li>
<font face="Arial, Helvetica, sans-serif">include rfax.jar in your CLASSPATH</font></li>
</ul>
</ul>
<h2>
<a NAME="sample"></a><font face="Arial, Helvetica, sans-serif">Sample application</font></h2>
<font face="Arial, Helvetica, sans-serif">RFax comes with a simple application
you can use to send your first fax. In order to start the application you
must just unzip rfax and execute the following file:</font>
<ul>
<font face="Arial, Helvetica, sans-serif">runSUN.bat </font>
</ul>
<font face="Arial, Helvetica, sans-serif">now you can send a test fax by doing
this: </font>
<ul>
<li> <font face="Arial, Helvetica, sans-serif">enter port name (COM1, COM2...)</font></li>
<li> <font face="Arial, Helvetica, sans-serif">select dialing mode (tone or
pulse)</font></li>
<li> <font face="Arial, Helvetica, sans-serif">select fax class (1, 2 or 2.0).
Check your modem documentation for this.</font></li>
<li> <font face="Arial, Helvetica, sans-serif">select flow control mode (RtsCts
recommended)</font></li>
<li> <font face="Arial, Helvetica, sans-serif">select command to set your modem
in RtsCts mode ( leave empty if this is the default for your modem). You should
check your modem manual to know which command you must select. If it is not
in the list you must leave it empty and enter the command as part of the "init
string"</font></li>
<li> <font face="Arial, Helvetica, sans-serif">enter destination of fax</font></li>
<li> <font face="Arial, Helvetica, sans-serif">press "Send fax"</font></li>
</ul>
<p><font face="Arial, Helvetica, sans-serif">you can receive faxes by:</font></p>
<ul>
<li><font face="Arial, Helvetica, sans-serif">enter port name (COM1, COM2...)</font></li>
<li> <font face="Arial, Helvetica, sans-serif">select fax class. (At the time
this document was written only class 1 is supported for reception.)</font></li>
<li> <font face="Arial, Helvetica, sans-serif">select flow control mode (RtsCts
recommended)</font></li>
<li> <font face="Arial, Helvetica, sans-serif">select command to set your modem
in RtsCts mode ( leave empty if this is the default for your modem). You should
check your modem manual to know which command you must select. If it is not
in the list you must leave it empty and enter the command as part of the "init
string"</font></li>
<li><font face="Arial, Helvetica, sans-serif">press "Receive". Now the progam
will wait for incomming faxes.</font></li>

<a NAME="send"></a><font face="Arial, Helvetica, sans-serif">How to send
faxes in your programs</font></h2>
<p><br><font face="Arial, Helvetica, sans-serif">The steps you must follow
to send a fax are:</font>
<p><b><u><font face="Arial, Helvetica, sans-serif">1. Implement the faxProducer
interface</font></u></b>
<p><font face="Arial, Helvetica, sans-serif">this interface will provide
RFax with the pages that must be send. The format of the interface is very
simple:</font>
<p><font face="Arial, Helvetica, sans-serif">
<i><font size=-1>public java.awt.Image getFaxPage(int page);</font></i></font>
<p><font face="Arial, Helvetica, sans-serif">You class must return a image
object that contains the data to be faxed. The maximum size the image is
1728 x 2387. If you use a size smaller than that you can use the
scale feature of the t4Encoder in order to scale your image. The scale
image shall not be larger than the maximum size.</font>
<p><font face="Arial, Helvetica, sans-serif">For example, if you image
is 800 x 1000 and you set scale to 2, the final image will be 1600 x 2000.
You must selec the resolution mode in FaxModem depending on the height
of the image.</font>
<p><font face="Arial, Helvetica, sans-serif">This is a simple implementation
of a fax producer:</font>
