Thank you Mitch!! The procedure I have been using and wrote about seems
to work roughly 50% of the time. Now I think I know why [:=)

Peter,
Skip is on to what you need to do, but that method won't show
everything. What you need to do is the following:
- Open up a DOS command window by clicking on the start button, then on
"run" and enter "cmd" and hit the enter button
- Copy and paste the following into the command line: set
devmgr_show_nonpresent_devices=1
- Then copy and paste the following, or manually start Device Manager
like Skip says: \windows\system32\devmgmt.msc
- Now go to the view menu and click on show hidden devices and you will
see everything that you ever installed
- Now you can delete everything that is in conflict and follow Skip's
instructions
I also have a nifty script that nukes all installed COM port drivers at
once as a worst case scenario. If you need that, send me a direct mail.
I don't read these postings all the time.

1. Open Control Panel and click on Hardware/Sound-->Device
Mangler-->Ports
2. In the View menu, click on Show Hidden Devices
If there are any, they will appear in the Ports display but grayed
out. Delete them, close everything, reboot, and try again. Windows
will occasionally, and without notice, leave a previous device
enumerated even after it is removed. It shows up as unavailable, or
in-use to a real device.
May not be your problem, but an easy fix. Best to remove all USB
cables before the reboot, then insert them one at a time while
watching the Ports display

The issue is far deeper than this. None of the COM ports work
normally after
starting the system. Occasionally the radio connects to the software
normally, other times it doesn't. If I have it working with N1MM,
close down
N1MM and try to start Commander (DX Labs) it won't work initially,
but if I
try it 3 or 4 times in a row it will connect normally.
Ditto with my two rotors. Those are the only serial ports in my
system. The
K3s, my 6m rotor (Rotor-EZ board in the controller box) and a Green
Heron
RT-20 (serial-to-USB, not pure USB like the newer RT-21). For whatever
reason, there is *something* holding all the installed/configured COM
ports
open and unavailable. I cannot find that "something."
