Windows PE Serial Port Driver

Does anyone have an insight into the serial port driver for Windows PE
- 2005 edition?

We need the serial driver to interface with touch screen hardware
during operation Windows PE. The touch screen is used by the operator
as the only available input device during Windows PE operation.

We are using Windows PE 2005, Embedded Systems OPK to generate a
recovery CD for a Windows XP Embedded device. The Windows PE OPK kit
number is X11-41588.

With or without the Windows PE Plug and Play option, the OPK generates
a Windows PE image that includes the serial port drivers serial.sys and
serenum.sys, along with most of the appropriate registry entries. One
thing that is missing is the device map contained in the key
HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM.

Because the device map is missing keys, we get an illegal device error
message when attempting to access the serial port If we manually edit
the hive to include the serial device map key values, then we get
device unavailable messages.

There was a note in the readme.txt file for earlier versions of the
Windows PE OPK that indicated that the serial port could be accessed
after using the DefineDosDevice function or using the full device name.
Neither method works for us.

This release note has since been removed from the readme.txt file in
the current version of the OPK.

Do you have any insights on how we can get the serial port driver
operational in Windows PE?
