If the program is written to handle 16 ports, then the answer is yes. Just because the ports are there doesn't mean that magically a program written for 2 ports will have an extra 14. > Q.

Okay, here's the scoop. The DLL library HAS BEEN REMOVED, according to the "Blue Ninja" at PC Expo, due to poor performance. SO...They have somehow built the calls into the system (I did NOT say "kernal"). Expect about an increase of 100% in performance for Windows applications running under OS/2 (versus its DOS 5.0 and Windows equivalent). I saw this first hand, so I'm not just making up numbers.
