- I have an I/O card ( a 100Mhz digitiser) hooked onto a PC. It operates
- by giving hardware interrupts at about (1000 to 4000 per seconds (in dos ). Is
- it possible to write an hardware interrupt service routine that will get
- called that frequently. If OS/2 has not time to do nothing else is not
- an issue. The interrupt service routine must get immediate CPU service and
- not be preempted by anything even though interrupts (from the board) are
- allowed to come through.
-
- My question is: Is this possible with OS/2? It now works with DOS but the
- rest of the software is becoming painful.

- Thanks
