ccport and wdmmdmld

hi, guys
I’m working on the usb modem driver for windows me(WDM), use ccport.sys and
wdmmdmld.vxd in the driver stack to bridge the difference(VXD<->WDM). As you
all know, we have no source code for ccport and wdmmdmld, so do you have any
method to debug this kind driver?

And I also wanna know, whether we need to handle COM related IOCTL code
(such as IOCTL_SERIAL_XXX) in our modem driver? (From NTDDK documentation, it
says that ccport provides some CDC Modem interface, so I’m not sure whether
this kind of IOCTL codes is also a blackbox like ccport and wdmmdmld).

Any reply is appreciated, thanks.

Best Regards

Jason
