@subsubsection Windows NT/2K/XP
@noindent
On Windows NT, 2000, and XP user applications cannot directly access the
parallel port. However, kernel mode drivers can access the parallel port.
giveio.sys is a driver that can allow user applications to set the state
of the parallel port pins.
Before using AVRDUDE, the giveio.sys driver must be loaded. The
accompanying command-line program, loaddrv.exe, can do just that.
To make things even easier there are 3 batch files that are also
included:
@enumerate
@item install_giveio.bat
Install and start the giveio driver.
@item status_giveio.bat
Check on the status of the giveio driver.
@item remove_giveio.bat
Stop and remove the giveio driver from memory.
@end enumerate
These 3 batch files calls the loaddrv program with various options to
install, start, stop, and remove the driver.
When you first execute install_giveio.bat, loaddrv.exe and giveio.sys
must be in the current directory. When install_giveio.bat is executed it
will copy giveio.sys from your current directory to your Windows
directory. It will then load the driver from the Windows directory. This
means that after the first time install_giveio is executed, you should
be able to subsequently execute the batch file from any directory and have
it successfully start the driver.
Note that you must have administrator privilege to load the giveio driver.
