Are you sure about that? It sounds a lot like the
coax or
twinax terminals that IBM made to go with 3270-controllers or
AS/400s (respectively). The ones I've seen which match your
description had an
RS-232 for a printer connection, but did their main comms
through the coax or twinax port out the back. I guess it
might be ASCII but probably isn't an RS-232 terminal.
Most 3270 & 5250 class terminals used printers that were similarly attached
(co-ax or twin-ax). Later models might have supported serial printers, but I
doubt it. There were several vendors who made "protocol converters"
specifically so that users could attach cheap parallel printers to their
mainframes and midrange systems. Andrew was one that I recall.
IBM also made some weird terminals that almost defy classification,
especially for word processing applications.
