I want to build some external circuitry and then be able to read/write
to that circuitry via the parallel port. I understand that this is not
necessarily trivial, but I've begun a simple little circuit with diodes.
What I really want to do is be able to read from a keyboard circuit.
Picture a 61 key keyboard. Basically I want to build a circuit that
will output a byte (actually I could read up to 4 keyboards, since I
have 256 values to play with) and then I want to read that byte with
the parallel port and then do some sound processing...
I realize that I can use ioperm with inb and outb from <asm/oi.h>. I guess the
question is this: is parport that much easier to use or won't it buy me that much?
After looking at the docs on parport, it seems like parport doesn't do much more
(functionally) than what I can do with inb and outb.
Thanks for any input!

Start at the beginning: what exactly are you trying to achieve?
