How to determine what com ports are being used?

[Blade]

How can I determine what is using my com ports on my HS machine?

Here is a list of the devices in the Device Manager:

I am wondering why some com ports are not showing up.

I am trying to find out why the WAF-NetCallerID script is saying that my com port 8 is already open, when I know that it is not.

I can run HyperTerminal and connect to the NetCallerID box and see the CID coming in perfectly, but not in HS.

The com port I have the NetCallerID box hooked to is com 8.

TIA

Open a dos prompt and type netstat /a that will give you a list of whats using what at that time

netsatat will only show network related connections, not local ports... I would look into a serial port monitor tool, there are quite a few free ones posted on the net. You could run that before starting HS and see if there is an data flowing...

Are you using opencomportex anywhere?

I do not use opencomportex at all.

Can anyone recommend a good serial port monitor?

I would just like to know what application is using the com port and if it is open or not.

Try Portmon from sysinternals...

I use a lot of their tools and they always work great.

Blade's issue is resolved - he was not aware of the difference in OpenCOMPort and OpenCOMPortEx, and Ex is used by WAF-NetCallerID with the default resource being 7, and he did have another device on COM7 opened with OpenCOMPort.
