The current version does not support COM ports from managed code.
If you know the Win32 API calls that are required, you can call these from
.NET using Platform Invoke.

Hi,

The only way that I know is to P/Invoke (Platform Invoke) the Windows32
EnumPorts APIs. There isn't anything in the .NET Framework that provides
this information.

This might help:

Dim moReturn As Management.ManagementObjectCollection
Dim moSearch As Management.ManagementObjectSearcher
Dim mo As Management.ManagementObject

moSearch = New Management.ManagementObjectSearcher("Select * from
Win32_POTSModem")
moReturn = moSearch.Get

For Each mo In moReturn
Debug.WriteLine(mo("Name") & " is attached to " &
mo("AttachedTo"))
Next

I tried this and cannot get VB.NET 2003 to work with this. I even find
references to :
Imports System.Management
in the Help files. But, still adding that outside the module in a Console
app. it still generates an error.
(sorry to jump in here but, this looked like an easy way to find the
commports.)
So, I am curious how you are getting this to work.

I think that Dart makes a nice .Net comm control if you don't feel like messing around with p/invoke.

Umm, whoops, I forgot to give credit where credit is due. Sorry. That code
was actually posted by a Mr. Ken Tucker on another Microsoft group (can't
remember where). Apologies, Ken. There's a glitch or two depending on the
OS, apparently.

If you want the full story (AFAIK), check out

Thanks Ken,
Mike
