I'll point you to the extended serial port support squeak map package.

http://map1.squeakfoundation.org/sm/package/36c286ee-c0af-4853-98a4

Although it's for serial ports, I guess you could subclass for parallel  
ports.
If you have unix you have everything you need.
If you have windows, then it's more work since the primitves for  
windows don't exist as far as I know.
