I was running the DOS version of ProComm under OS/2. There was some, admittedly obscure, setting that had to be changed in the program profile to permit direct hardware access. Once that was done it worked fine. In fact, doing some comm software testing, I ran ProComm in it's host mode to out one comm port to a modem, and my test software through another comm port to another modem and dialed up my own machine. I used my OS/2 system mostly as a development platform for DOS programs and a few Windows apps as well.
Mostly legacy machine control or financial applications these days.
Perhaps. I didn't play a lot of games.
Your experience was rather radically different than mine and, apparently, others.
Modems, printers, scanners, machine tools, that sort of thing.
The few games I used ran fine, with a couple of exceptions. But I did hear this particular complaint quite a bit at the time.
