- Our company, LABTECH, is the developer of a data acquisition software
- application package which runs on DOS and OS/2 (LABTECH NOTEBOOK).
-
- If you think you can take a data acq app that is currently running on DOS
- with a 250 Hz interrupt rate, and get two of those to run in real time in
- two OS/2 "DOS boxes", you're mistaken. The DOS boxes won't run in real
- time at all because they are being time-sliced with each other and with the
- rest of OS/2. The timer ticks are virtualized, and do not track in real time.
-
- Sorry, but I don't think this plan will fly..
