Hi Bob,
No humour intended (!), here's some C++ code, it's really very simple, sadly
some formatting will be lost in the mail below. This really is the most
fool-proof way of listing COM ports which exist on a computer:
for (UINT nPort = 1; nPort <= 255; nPort++)
{
//
// Form the Raw device name.
//
CString strPort;
strPort.Format(_T("COM%d"), nPort);
COMMCONFIG cc = {0};
DWORD dwSize = sizeof(COMMCONFIG);
if (GetDefaultCommConfig(strPort, &cc, &dwSize))
{
// Add strPort to the list
}
}
