      Thanks for your suggestions. I highly doubt it is a conflict though
      because I currently have no other devices on the COMs. Device Manager
      doesn't report a conflict either. But nonetheless I'll reverify this

      Also, I'll give the FIFO buffer mod a shot too. Frankly not too hopeful
      here either as I can talk to the weather station (with FIFO buffers on)
      but only after that manual uninstall of the com port and reboot.
      Definitely worth a shot though.

      Just as a reference, I thought Microsoft's knowledge base article
      #283063 had similarities to this problem, though not exactly (and it was
      Win2K, not XP). I did however try the registry change to no avail.

      I'll also have to look into that IO Gear USB/Serial you mentioned.

      Again, thanks for the input, I'll explore a little more.
