no, they make cards so that IBM PC's can emulate being this type of
The chip contained on some of the cards can be use to run one of the
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 goes on
wire, but the actual data protocol is not published by IBM.
I have a product that will capture the interchanges on the wire. One
might rig up a
utility to do that with a bit of programming with one of the interface
cards that are
available, if you were to try to reverse engineer what is on the wire.
This would assume of course you had access to a mainframe communicating with
one of the terminals.
