Serial Services and DevB on PC

| Hi,
I had a nice working Serial Service and Com port set up in Windows XP SP2
Bluetooth, then I deleted it, and now I can't successfully add it back. It
used to be set up for COM6 and COM5 and my Bluetooth device showed DevA and
DevB. I clicked Add Serial Service and Add Com Port (COM9 and COM8 now) but
my application that used to work no longer works, AND I don't see Dev B
anymore. I'm positive having DevB must be key to making this work. Any ideas
how I can get DevB to appear for my Bluetooth device in My Bluetooth Places?

| You can disregard the last message. It turns out Windows XP has a bug that
keeps accumulating Bluetooth ports (numbers keep getting bigger).
To fix this I did the following:
1. Go to Control Panel, System. Click the Advanced tab > Environment
Variables.
2. In the System Variables box click New: Variable name:
devmgr_show_nonprese
nt_devices, Variable Value: 1
3. Now you can see all the COM ports in the Device Manager. To delete those
COM ports click the hardware Tab -> Device Manager.
4. In the menu click View -> Show Hidden Devices
5. You can now expand the 'Ports(COM & LPT)' tree and see all the extra COM
ports: Right click & select 'uninstall' to remove each individually.
Now when I set one up it worked.
