Can you get it to do TN3270?
Those IRMA boards implement a 3270 hardware interface...nothing to do with
IP. TN3270 (as you know) is effectively 3270-over-IP.
The 3270 hardware protocol uses coaxial cables and BNC connectors.
Upstream from terminals and printers are usually found "establishment
controllers", like 3174s, etc. They connect to a host (mainframe) via either
a LAN connection (Ethernet or token ring), serial bisync over a modem or
direct connection, parallel channel (an older high-speed IBM mainframe
controller interface), or some other method.
That interface board allows one to connect a PeeCee (or a Mac, or whatever
it's for) to one of those establishment controllers.

Those are for
lack of a better term for them, terminals.
I still think that "TERMINAL" is a better name than "thin client"
