Serial driver doubts

Hi,

I am developing (actually just started) a WDM driver for serial port . The
requirement is to develop a driver with which one can send and receive
TCP/IP packets over the serial port.

I have following doubts :

  1. I am using the WDM sample (Ndis_Usb) provided by Eliyas. Is this the
    correct sample to start with for my requirement, or should I use any other
    sample?

  2. How to debug a serial driver? The standard debug setup uses serial ports
    for communication between host and target machine. So how to debug serial
    using serial itself ?!

  3. In my initial try, I am getting the status
    ‘STATUS_INVALID_DEVICE_REQUEST’ when I issue URB_CONTROL_DESCRIPTOR_REQUEST.
    What is going wrong ?

Any response will be greatly appreciated.
Thanks,

Regards,
Abhijit
