My FAQ response:

.NET has no support for legacy ports (COM/LPT)
You have to use PInvoke or Interop...

First understand the Win32 API as described here (C++):
http://msdn.microsoft.com/library/en-us/dnfiles/html/msdn_...

New MSDN article for .NET (mostly C#):
http://msdn.microsoft.com/msdnmag/issues/02/10/NETS...

PInvoke samples for C#:
http://msdn.microsoft.com/msdnmag/issues/02/10/NETS...

or for VB.NET:
http://msdn.microsoft.com/library/en-us/dnvssamp/html/vbcs_usingthecomporti...
http://www.gotdotnet.com/userarea/keywordsrch.aspx?key...
http://www.allapi.net/classlib/class...

or you can use the "Managed Extensions for C++" and write wrappers.
http://msdn.microsoft.com/vstudio/techinfo/articles/upgrade/mana...
http://www.gotdotnet.com/team/...
on your VS.NET path:
...\VC7\managedextensionsspec.doc
...\VC7\migration_guide.doc
MC++ Sample:
http://www.codeproject.com/managedcpp/howtoc...

or reusing the VB6 MSComm ActiveX is easy, but it has some 'problems' (license)

for Interop, use newsgroup:
microsoft.public.dotnet.framework.interop
