The address of the parallel port where the LCD is connected.

The first standard parallel port address is 0x378.
The second standard parallel port address is 0x278.
The third standard parallel port address is 0x3BC.

You can specify a different address if you need.

If you don't know what I'm talking about, load the parport module,
and execute "dmesg" or "cat /proc/ioports". You can see there how
many parallel ports are present and which address each one has.

Usually you only need to use 0x378.

If you compile this as a module, you can still override this
using the module parameters.
