no, they make cards so that IBM PC's can emulate being this type of terminal. The chip contained on some of the cards can be use to run one of the terminals, in a limited fashion, but the protocol is not widely available (for the wire). The software spec of what goes on is out there, and you can get some of what

on the wire, but the actual data protocol is not published by IBM.

I have a product that will capture the interchanges on the wire.
