That's odd that it can send but not receive. The link port on the 89 is cheap. It gets bent really easily. Mine doesn't work at all anymore. (It's out of warrantee, so I'm just taking it apart and fixing it.) I seriously doubt it's anything software related though. Does it work if you receive from another TI-89?
