it would even work on NT 3.1: http://support.microsoft.com/kb/102988

Please add a null check for "subkey" after

RegistryKey subkey = 
Registry.LocalMachine.OpenSubKey("HARDWARE\\DEVICEMAP\\SERIALCOMM");

and consider the "using" pattern.

Shouldn't be the default port name the first entry of this
list? Your patch presets "COM1".
