Dear All,

Iam writing a serial driver for a touch screen device. It is
basically a port driver like the sermouse driver for the serial mouse. Can i
layer this driver on the serial----serenum stack and make mouclass as its
upperfilter?

If so, pls let me know the registry entries i need to add.

would be very thankful for ur help…
Seshu.

It sounds like your device is not serial enumerable. If it is, then
serenum would enumerate your device and then you install your driver as
the FDO and set the device class to the Pointer device class INF.

If your device is not serial enumerable, you can install serial.sys as a
lower filter for your device and set the device class to the Pointer
device class in the INF.

By setting the device class to the Pointer class mouclass automatically is
loaded on the stack.
