------- Additional Comments From juan_lang@yahoo.com 2007-03-05 23:25 ------- There are lots of ways apps look for serial ports. Some just use CreateFile directly, and these should work fine. Some poke around in the registry, some use setupapi. You might try getting a +registry,+setupapi trace to see if it's doing either of the above. Vitaliy suggests one set of registry entries that might help; there are others.
