I know it is along time ago, but on OS/2 2.0, what did you use for 3270 emulation on that time? Communication Manager/2? Or was it already available Personal Communications for OS/2 ? or any other software?

I don't remember the details. Using a PC with 3270 emulation was a common thing, by the time they got around to using one as a terminal for mainframe service, but it was more common in windows. That was during the days when IBM was actually supporting OS/2, so the driver, and supporting software, was available for OS/2. I am sure that it was cost justified, and the engineers realized that they could also use the serial communications, if it was ever needed.

As I said, there was nothing unusual about using OS/2 with main frames. It was just another dumb terminal, with a few extra things that it could do. Many customers took a look, and realized that they had been using the same thing for a few years. All the "brains" were in the support processor.
