DMA operation and IoConnectInterrupt?

OSR_Community_UserOSR_Community_User Member Posts: 110,217
If I have a driver for DMA (serial port) and device that doesn't have
ability to interrupt (data transfer is handeled by length variables and
watch dog timer)
do I need to use IoConnectInterrupt and creating DPC routine?
Can somebody answer and explain that to me?

Regards,
Neno

    No, you do not need IoConnectInterrupt, but you will possibly need a _timer_
    DPC routine.
