Hello,

i'm trying to write a based interrupt driver for an ISA synchronous comunication card running in a Win98 OS. I've already donde a "driver" in visual c++ 6.0 that reads the card ports using the "polling" technique (while (!finished) readPort() ) . This technique is giving me a lot of hassle.

So i need to go a bit further, and i'd like to receive a notice when data arrives, instead of asking if data has arrived. I mean i want to handle the interruption the card generates and transmits to the SO when data has arrived.

I'm not sure if i need the DDk in Win98, i think it's just a question of using the proper C/C++ functions.

Any comments or ideas would be of great help.

THANK YOU.
