Alex, have you considered getting a used terminal controller for your IBM
3290? It looks like an IBM 3174 would work.
According to IBM Publication No. GG24-3061 (Revision -05 is the latest I
can find), the IBM 3290 requires a "Downstream Load (DSL) Diskette." This
feature in turn requires any o

"Efficient" how? Bandwidth? That's cheap now. 3270 data streams were fun
because they were so complex. But expensive to program and use. And the fact

Alex,
What you have in that interface is a simple protocol translator ...
translating bi-directional TN3270 to 3270 Data Stream. That is great to
drive a 3270 dumb terminal.
The first thing you need is to emulate a real control unit ... like a 3174
or 3274.
