This has all got me re-examining the 3270 data stream and wondering... ... Did anything else ever use the 3270 data stream - other than IBM mainframe operating systems?
It's such a nice efficient data stream that one might like to use it from other platforms. But I wouldn't know how to set up a server x3270 could talk to.
