I too am developing PC software that uses the National Instruments GPIB card. Actually, it supports either the H-P card (with a TMS9914 IC, which is well documented in the TI data book) as well as the National Instruments card. However, my application doesn't require calling any drivers inside ISRs so I can't offer you anything except my sympathy. But if you learn anything about the N.I. card, I'd like to know it too. One technique you may try, however, is to set a flag inside the ISR and exit quickly. Then call the driver from outside the ISR if the flag is set. That's easy with a multi-tasking operating system, but not impossible with DOS. Perhaps you've already tried this; if so, pardon me for stating the obvious. Regards, Joe dubner@hpspkla.HP.COM
