program requires an inpout32 DLL. You can use either my original version, which
works only on Windows 95/98/ME, or the version from LOGIX4U, which works on
Windows 95/98/NT/ME/2000/XP. Both are available from:</o:p></font></p>

<p class=MsoPlainText><font face="Verdana, Arial, Helvetica, sans-serif"> Inpout32
was developed to allow access to parallel ports and other ports on custom hardware,
but you can use it to attempt to access any hardware that is mapped as an I/O
port.</font></p>
<p class=MsoPlainText><font face="Verdana, Arial, Helvetica, sans-serif">Use the
DLL at your own risk. Writing to hardware port addresses can result in system
crashes, loss of data, and in some cases, even permanent hardware damage.</font></p>

the Application</o:p></font></h2>
<p class=MsoPlainText><font face="Verdana, Arial, Helvetica, sans-serif"><o:p></o:p></font><font face="Verdana, Arial, Helvetica, sans-serif">To
run the test program: <o:p></o:p></font></p>
<p class=MsoPlainText><font face="Verdana, Arial, Helvetica, sans-serif">1. Obtain
inpout32.dll as described above and copy the file to your Windows system directory
(usually \Windows\system32). <o:p></o:p></font></p>
<p class=MsoPlainText><font face="Verdana, Arial, Helvetica, sans-serif">2. In
the VB6 environment, open the project Test_InpOut32.vbp.<o:p></o:p></font></p>
<p class=MsoPlainText><font face="Verdana, Arial, Helvetica, sans-serif">3. In
the Form_Load subroutine, set PortAddress equal to the port address you want
to test. <o:p></o:p></font></p>
<p class=MsoPlainText><font face="Verdana, Arial, Helvetica, sans-serif">4</font><font face="Verdana, Arial, Helvetica, sans-serif">.
Run the application. Clicking the command button causes the program to write
a value to the port, read the port, and display the result. The value increments
with each click, resetting to 0 at 255.<o:p></o:p></font></p>

<p class=MsoPlainText><font face="Verdana, Arial, Helvetica, sans-serif"><o:p>1</o:p></font><font face="Verdana, Arial, Helvetica, sans-serif">.
Add inpout32.bas to your Visual Basic project. <o:p></o:p></font></p>

Use this syntax to write to a port: <o:p></o:p></font></p>
<blockquote>
<p><font face="Verdana, Arial, Helvetica, sans-serif">Out PortAddress, ValueToWrite
<o:p></o:p></font></p>
</blockquote>
<p><font face="Verdana, Arial, Helvetica, sans-serif"><o:p>Ex</o:p></font><font face="Verdana, Arial, Helvetica, sans-serif">amples:<o:p></o:p></font></p>
<blockquote>
<p><font face="Verdana, Arial, Helvetica, sans-serif">Out &h378, &h55
<o:p></o:p></font></p>
<p><font face="Verdana, Arial, Helvetica, sans-serif"><o:p>Out 888, 85</o:p></font></p>
