LPT Manager is a program that allows you to control the parallel port.
It shows the current state of every single I/O line of the port
with LEDs or, optionally, with the corresponding registries' values.
You can also interactively change the status of output lines, with a
mouse clic or writing directly a value into the registry.
Primarily developed on Linux in C, it uses the GTK+ 2 for the
GUI, but a port to the Win32 platform is available.
LPT Manager is released under the GPL.
Released version 1.1. This version adds support for IO.DLL
as another method (now the preferred) for I/O access under WinNT.
The development is currently stopped, because I don't have
time to work on this project.
