I wish to find subkeys within the registry.
For example it appears to me that the comm ports are in
HKEY_LOCAL_MACHINE\Enum\BIOS\*PNP0501\

* but there are subkeys for each comm port

e.g.
HKEY_LOCAL_MACHINE\Enum\BIOS\*PNP0501\0A
and
HKEY_LOCAL_MACHINE\Enum\BIOS\*PNP0501\0D

on one machine and
HKEY_LOCAL_MACHINE\Enum\BIOS\*PNP0501\0B
and
HKEY_LOCAL_MACHINE\Enum\BIOS\*PNP0501\0E

on another

I am able to find the data I wish out of these but my problem is
finding the subkeys e.g. \0A and \OD

Thoughts?
