I have build the serial driver shipped with NT ddk and
I installed it on my system. It showing the ports. But
it is not performing any read/write operations on the
port. Is the driver not fully functional? Please send
any reference links to the fully working serial driver
examples.
If I want to create a COM port of my own and handle
the operations on it, where should I modify on the
source files(Which file and which function).

Chandu,
The serial driver(from NT DDK) is a good sample
to start with. I would suggest you take the serial
driver of Win2k DDK which is the enhanced version, the
enhancement includes PNP and Power handling and
others.
As far as your problem is concerned, check the IRQL
and IO address mapping when you load the driver. It
won’t work, if there is a resource conflict. Check
this first in the Device Manager settings.
Is this driver going to handle any hardware or is it
just a virtual port ?
Cheers,
Jay

If you are running NT 4.0 and built the serial.sys driver from the NT DDK, you will be able to copy the serial.sys file over the one in the \winnt\system32\drivers, restart NT and use the driver. It does work!

Thanyou Dev,
I have to just create the port and handle read/writes
on the port. There is no hardware mapping.
Can you suggest some way to do this.

Chandu,
Use the Win2k serial driver and remove the
hardware related stuff. I understand that it is a bit
complicated driver and not easy to remove the
unnecessary. The good approach I often follow is write
a skeleton driver which will support the required IRP
Major functions, put some default handling for the
IRP, Create a device object and export symbolic link.
That’s it i have a driver ready, later add the flesh
to match my requirements.
So, on these ideas create a skeleton driver with
Ntdevice - \Device as some \ChanduSerial5 and DOS
device name \DosDevices as \COM5. Install the driver
and you have a COM5. Add the required later.
I apologize for “ChanduSerial5”.
Cheers,
Jay
