Out-Of-Band communication with Wan Miniport Driver

OSR_Community_UserOSR_Community_User Member Posts: 110,217
Hello,

I am developing a WAN Miniport Driver. I have a requirement to do a
out-of-band (similar to IOCTL in case of SCSI miniport drivers)
communication with our WAN miniport from an Application running in User
Mode. Out-of-band communication will be implementation specific
operation on the Hardware.

What are the ways one can go about implementing the above out-of-band
communication.

Thanks in Advance.

    Hi,

    I am resending this email with more description, can any one throw some
    feedback on this.

    I am designing a WAN Miniport Driver. I have a requirement to do a
    out-of-band (similar to IOCTL in case of SCSI miniport drivers)
    communication with our WAN miniport from an Application running in User
    Mode. Out-of-band communication will be implementation specific
    operation on the Hardware.

    Is it possible to do an out of band communication ?

    What are the ways one can go about implementing the above out-of-band
    communication.


    Is this approach possible:
    Can there be a kernel component which provides a upper edge interface
    through IOCTL and lower edge talk to NDIS.

    Is it also possible to keep the protocol driver and other in reset state
    and do some diagnostics on the hardware and bring them back without any
    side effect.



    Thanks

    Yes, you must write a simple protocol driver with lower layer NDIS interface.
    This driver implements your user mode API and call NdisRequest to pass this
    request to your WAN miniport driver.

    Only with a protocol driver you can send requests to your WAN driver in
    Windows 98.

    A second way are special TAPI device requests.
