pc interrupts with vb6

Posted 30 September 2009 - 07:44 AM

How does one write an interrupt handler for VB6. I have this sync HDLC card that generates interrupts upon reception of frame. I would like top know the steps required to write a handler for this interrupt. I am successfully using vb6 to communicate with the card by using APIs CreateFile() WriteFile() ReadFile() and DeviceIoControl(). I am able to setup, write(send data) and read(receve data) from the sync HDLC card one frame at a time. If I try to poll the sync HDLC card the performance drops by the speed of the polling. The computer that I am using is running XP and the sync HDLC card is on the PCI bus. Any help on this would be appriciated. Thank You
