Thread in driver ??

Hi All !
Anyone has worked with Numega Studio to write a Driver ?
I must write a Driver filter for Com Port and synchronize system time
between 2 computer via Com port ( call them Server and Client ). In the
server side , there is one User application to active the driver and User
can click on a Button in application to tell the Driver to implement
synchronization time with the Client .
In the Client side , There is no application , only Install Driver . And the
Driver in the client side must use a Thread to detect when the Signal from
server has come .
SO, My task now is that I must create a Thread in Driver in order to detect
when the signal has come to the Port .
Pls explain , how can i do this work? I have create a Thread and put it in
the DispatchCreate ( I use Numega to write driver ) . So now , How can I
detect the Signal came to the Port by this Thread?
Pls explain the Mechanism !
Thanks in advance !

Why drivers? This task can be done in user mode only.

Then why creating threads? Just call ZwCreateFile on \\.\COM1 or such, and
then ZwReadFile.
This will work, and will be enough to satisfy the teacher.

by the way , I have a fragment of code like here . But I don't know why it
could not open the file !
Thanks for your help !


#define FILE_NAME L"c:\\1.out"
KUstring fileName((PCWSTR)FILE_NAME);
KFile m_File ;
NTSTATUS openStatus = m_File.OpenCreate(
fileName,
NULL,
FILE_GENERIC_READ | SYNCHRONIZE,
OBJ_CASE_INSENSITIVE,
0,
FILE_SHARE_READ,
FILE_OPEN,
FILE_NON_DIRECTORY_FILE | FILE_SYNCHRONOUS_IO_NONALERT
);
if( !NT_SUCCESS( openStatus ) )
DbgPrint("Error open file ");
