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
goes on
on the
wire, but the actual data protocol is not published by IBM.
GA23-0061 (3274 control unit description and programmer's guide) or
something later?
I have a product that will capture the interchanges on
the wire.
Are these all derivatives of the 3274 and its protocol?
What were the various "IRMA" cards?
I have some protocol docs in the 3274 FE manuals.
