John,

Are you using a serial comm component of some type? Does it have a method
for opening a COM port? I'm using an old C++ Builder shareware component
called ZComm (still available), and I use a brute-force method to make a
list of available COM ports, as outlined below. Note that the resulting list
will not contain COM ports that exist but are already in use.

Joe

for (int i=1; i<=256; i++)
{
    if (open_com(i) == true)
    {
        add i to list
        close_com(i)
    }
}
