I was just asking myself this same question. I found an answer at:
http://www.borland.com/devsupport/delphi/qanda/FAQ1774D.html
Basically, look in the registry under
HKEY_LOCAL_MACHINE\hardware\devicemap\serialcomm, which is refreshed at each
boot.
I don't know if its the definitive solution though, but short of TAPI, what
other options are there?
