Device::ParallelPort::drv::auto - Automatically choose driver.


        use Device::ParallelPort;
        my $pp = Device::ParallelPort->new('auto:0');


This module should be used if you do not care what driver is used. It is very handy for writing cross platform applications in that it will autoamtically determine which parallel port driver is appropriate.

See Device::ParallelPort for full details.


The current nature of it requires modifications to this module to add new drivers. Longer term it would be better if it tried each driver installed on the system in turn allowing new drivers to add their own interfaces.

As such, the current version only detects between three drivers.

        * parport - If linux and has a writable /dev/parportX
        * linux - If linux and running as root (and no parport)
        * win32 - If running on windows

NOTE - You MUST have the driver mentioned above loaded on your system for this to work. They are each SEPARATELY available in CPAN.
