Accessibility Options - Serial Keys - Comm Port Problem

[bo]

I have an external input device that I want to use on my computer.
Dell running Windows XP Pro. For whatever reason, when I hook it up
it automatically gets assigned to COM5, 9, 11 or some other high
random port number.

The problem is, in order for it to even work, I will need to go into
Accessibility Options / Serial Keys and enable it, but my only choices
for COM ports are 1-4. (so you see my dilemma?)

Is there anyway to get Windows (Accessibility Options) to recognize/
see the higher port numbers?

OR

How can I get this device to utilize COM 2, 3 or 4?

By the way - under device manager >> Ports: 2, 3 & 4 aren't even
listed...

I'm stuck....

any help, advice, feedback or suggestions would be very much
appreciated!

To clear the incorrect COM ports in Device Manager, delete all the inactive
COM ports in Device Manager. The next time that you start your computer, the
COM ports are detected correctly.

Also check your settings via the BIOS.

/NOSERIALMICE=[COMx | COMx,y,z...] - Disables serial mouse detection of the
specified COM port(s). Use this switch if you have a component other than a
mouse attached to a serial port during the startup sequence. If you use
/NOSERIALMICE without specifying a COM port, serial mouse detection is
disabled on all COM ports.

Yep.

I run into this all the time, as a critical piece of software (and older
version) I run at work only sees COM 1-4; newer versions don't have this
limitation, but I'm not inclined to spend nearly a grand for that "feature".

see the higher port numbers?

No, but you can shift the port number down in a few seconds.

Connect the device so that it creates its port. Go to Device Manager,
right-click on the port, choose Properties.

Choose the Port Settings sheet, and the Advanced button. Change the COM
port button in the lower left.
