Request for help: ClipOn Organizer

Hello.

I hope someone can help me:

I have a clipon Organizer for which I've lost the connection cable
which is used to transfer data. If I remember correctly, this is a
serial cable with a standard DB9 serial connector at the PC end and a
two-conductor mini-plug at the Organizer end.

I've called Motorola along with local service centers...a replacement
cable is only sold bundled with the software (which I already have)
and is really expensive.

Can some kind soul out there who has one of these with a continuity
tester tell me which pins on the DB9 are connected to the tip/shaft of
the plug, so I can make one up?

Thanks very much!
