Many thanks for your quick reply, Richard!
Supporting XP would be nice; I still have a couple of old laptops -- with real serial ports  -- that prefer this aging version...
What's the best way to get Windows version from within bb4w?

Hi!
It looks like Windows Win32_SerialPort WMI class miserably fails to detect and list most of virtual serial ports (e.g. over an Ethernet link, such as Tibbo), and more annoyingly USB-to-serial adapters, such as ATEN or Prolific.
Any idea about which method could be used to let Windows (and BBCBasic) nicely list what is reported in the "COM ports and LPT" section of the Device Manager?
Thanks,
R.

I don't think you should blame Windows, it's more likely that some 'virtual' serial ports fail to follow the rules when they install themselves. After all, you can pretty much guarantee that all serial ports on a modern PC are 'virtual' so it would be daft if WMI never worked.

I answered that before: "I fear that if you can't make the WMI method work you will have to fall back to reading the Registry". But you would be entirely justified in using WMI and simply saying that your software is incompatible with 'non-conforming' virtual port drivers.
