Application "ParaPortUtility.exe"

Overview

ParaportUtility is a simple dialog box based windows application which can be used to set or clear pins on parallel port connectors. To be operational, the application needs the driver "ParaPort.sys" installed and the "ParaPort.dll" must be visible to "ParaPortUtility.exe".

Graphical User Interface ( GUI )

The GUI consists of the following sections:

• "Port Parameter" to select of the parallel port. The available ports of the computer are displayed in the combo box.
• "Data Register" to read ( "Input" ) or write ( "Output" ) a byte on the parallel port. The byte can be specified as hexadecimal value or with check boxes.
• "Status Register" displaying the state of the 5 input lines.
• "Control Register" to set or clear the 4 output control lines.
• On the bottom of the dialog box, there is one button "Execute Cycle" to transfer Data to/from the parallel port and a second to exit the application.

A checked box in the "Data Register", "Status Register" or "Control Register" ( e.g.: like "Pin9: D7" ) means that the correspondent pin on the parallel port connector has 5 Volt TTL. An unchecked box means 0 Volt TTL.
