1. I am using an IBM Thinkpad A31p with Windows XP Professional.
2. I have a Logitech PS/2 MarbleMouse (trackball)
3. The Thinkpad has no PS/2 port.
4. As I have no PS/2 -> USB adapter (and not near where I could purchase one), I am trying to use the mouse via a PS/2 -> Com port adapter. I have activated 'serial port' in the BIOS, But there is no response to the mouse from the ThinkPad.
5. What do I have to do to get the mouse to work?

Thank you.

Go with the flow, get a USB mouse. The adapter may cos more then a mouse.

Thank you, but not helpful, as I am not in a location where I can purchase or easily receive a new USB device.

Set TrackPoint to AutoDisable

Go to your BIOS(F1 when the laptop start). Config menu...Keyboard/Mouse...TrackPoint must be set to AutoDisable.

i think it's a thinkpad issue. i believe the thinkpad's take a special mouse adapter. i would search for mouse/keyboard adapter on the ibm website in the parts section. the cheapest one i've found was $15. they go as high as $35, i believe... you can easily buy it over the internet...

As far as I understand as the Trackball is a PS/2 - serial device a PS/2 - serial adapter, which I have - should work, but doesn't.

It depends on the version / revision of the Marble Mouse that you have.

I have not seen ANY 3 way compatible mice.

They are either PS/2 and serial, PS/2 only, or PS/2 and USB.

Check with Logitech, and verify what protocols your device supports.

If you need a PS/2 to USB adapter, Cyber Guys

sells them for $1.99

This is a PS/2 - serial, but it is not functoning with a serial adapter to the serial (com) port.

First, have you verified the serial port in device manager?

Have you tried installing Logitech's Mouseman software?

Do you know that the trackball works?

Have you tried a different mouse on the adapter?

Just trying to eliminate all possibilities.

Thank you. In fact, the probem was solved late yesterday when in this most unlikely place someone found a Logitech PS/2 -> Serial adapter. A PS/2-> serial cable will mot work. A PS/2-> Serial Microsoft mouse adapter will not workO only Logitech's pin-outs match. And with Windows XP even Logitech's Mouseman software will not work.
