I'm trying to do some LPT interfacing with the few components I have and I was wondering if anyone knowledgeable in the field of gr11/12 computer engineering (as they call it) can determine what the compile error "Unable to find I/O port at address [4]" means? Also, assuming I get things working, which pins of the DB-25 (parallel connector) does Turing recognize as data input, and which are data output. I cannot recall from last year. All help appreciated. Thanks
