Dear All,
Anybody can point me how to get the com port count in kernel mode.I am writing a virtual com port driver for win98 and win2000,I need to get the curren com port number and create my com port number.If the config manager function can used to implement it?
Any advise will be appreciated!
Best Regards,
Black
This is a very unreliable method to determine the com port number you want to expose. Consider that a modem is not plugged in when you determine the com port number and you use the same com port number as the modem. When the modem is plugged in, the modem no longer works. On windows 2000, if you install under the ports device class, a unique com number will be installed for you upon device installation. If you install under your own device class, then there are APIs which you can call in your device installer DLL which will give you a unique com name.
You can retrieve this com number by calling IoOpenDeviceRegistryKey in IRP_MN_START_DEVICE to open the device instance key and then query for the value “PortName”, which will be returned to you as a string, in the form of “COMX”, where X is a decimal value. You don’t actually have to inspect the value that is returned, all you need to do is append the value to "\DosDevices" and create the symbolic link with that string.
As for win98, you are on your own. Perhaps some devs who are more familiar with ccport know of a solution for that platform.

Thanks for you response,
Because I have writed a com port enumerator to emum my com port.I have to confirm there is how many com port on the system.So that my com enumerator can
create new device node(CM_Create_DevNode) for my com port use the last com number.for example if the system have com1 and com2,I will create the com number is com3.Thus I have to enum all com port on system,I want to search registry to find the current com port number,But it seem too trouble.
Do you have any advise.

Is it possible to install under the ports class but inhibit the unique com
number generation, particularly say in Windows XP?
This is desirable to allow users the ability to assign their own com number
to a port during device installation, rather than requiring them to wait and
go to an advanced property page.

My OS is win98,My device is a usb device,I use it to virtual a com port.
Now I have implement a USB driver and a serial driver ON win98,and I call the CM_Create_DevNode function to create a com device node in usb driver.I hope can implement the com port PNP function with this method.But I need to choosing a com port number.so I ask this question.

I’m not sure about Win98 or Win2000, but look at the
${DDKHome|}\src\setup\pnpport sample in the ddk. It demonstrates using
ComDB functions, which may only be present in the latest DDK and functional
in WinXP. I currently am using these functions under WinXP, but am see
double COM number usage, probably because of the port class assignment Doron
mentioned, hence my desire like Mr. Lee to control all COM number
assignments for my port.
I do know that the ComDB value under
“HLKM\System\CurrentControlSet\Control\Com Name Arbiter” is a bit masked key
used in Win2000 and WinXP to determine what COM numbers have been assigned.

No, it isn’t possible to suppress the generation of the com port number,
but what you can do is in the post processing of DIF_INSTALLDEVICE,
present the dialog, release the com port number that the ports class
installer gave the device and claim the new one. After you claim the
new one, write it into the appropriate registry location and call the
same APIs that the advanced dialog does to reenumerate the stack.

Typing “com port enumeration windows 98” into google, I got the following 2 hits rather quickly:
http://www.codeproject.com/system/listports.asp
http://www.codeproject.com/system/enumports.asp
Why can you not use the devnode created for your usb device for the com port? This way there is no need to manually create another one.

Because, as you pointed out with the modem example, certain applications
expect to communicate with devices on specific COM ports. As our customers
migrate to a newer OS, they still need for their applications to properly
execute, and sometimes, if not often, an unfortunate side effect of this is
that they require the ability to do so on specific COM ports. Since these
folks butter our bread we need to accommodate them in a windows environment
and attempt to find solutions which allows them to do this.

install under the ports device class, a unique com number will be installed
for you upon device installation. If you install under your own device
class, then there are APIs which you can call in your device installer DLL
which will give you a unique com name.
You can retrieve this com number by calling IoOpenDeviceRegistryKey in
IRP_MN_START_DEVICE to open the device instance key and then query for the
value “PortName”, which will be returned to you as a string, in the form of
“COMX”, where X is a decimal value. You don’t actually have to inspect the
value that is returned, all you need to do is append the value to
"\DosDevices" and create the symbolic link with that string.
As for win98, you are on your own. Perhaps some devs who are more familiar
with ccport know of a solution for that platform.
