- Ok, for anyone following this thread, we now have a couple of posts, one saying
- most parallel ports are made for "output-only", one saying read-write.
- for my 2c. I figure that most must be read-write. I've used both the parallel
- port tape backup and the lan-pocket-ethernet card. I've not seen a machine that
- wouldn't work with them.
- I had also heard rumors about cheap, output only parallel ports.
-
- Can anyone else explain/unravel the mystery of the output-only port?
