I found this whilst surfing the web, I found it useful and as it was not on Aminet,
here it is. It contains assembler function, callable from a C progrm to access the 
Amiga parallel port.

You can use the supplied software with DICE, PhxAss and ManxC. I could not get it to work 
with Storm C but I have only recently got it on my Developer CD.

   The following C functions are provided:

      getport  -- Get   parallel port access
      freeport -- Free  parallel port access
      portdir  -- Set   parallel port data direction      (0/1 = Input/Output)
      portddr  -- Set   parallel port data direction bits ($00-$FF)
      rdport   -- Read  parallel port data                ($00-$FF)
      wrport   -- Write parallel port data                ($00-$FF)
      busydir  -- Set   BUSY control line data direction  (0/1 = Input/Output)
      rdbusy   -- Read  BUSY control line state           (0/1 = Low/High)
      setbusy  -- Set   BUSY control line state           (0/1 = Low/High)
      poutdir  -- Set   POUT control line data direction  (0/1 = Input/Output)
      rdpout   -- Read  POUT control line state           (0/1 = Low/High)
      setpout  -- Set   POUT control line state           (0/1 = Low/High)
      seldir   -- Set   SEL  control line data direction  (0/1 = Input/Output)
      rdsel    -- Read  SEL  control line state           (0/1 = Low/High)
      setsel   -- Set   SEL  control line state           (0/1 = Low/High)
