After 2 weeks, I got the bluetooth stack installed in WINDOWS 7. For about $15, I bought a Cirago Bluetooth USB adapter, (BTA-3210 V2.1)
It came with a disk that had the bluetooth stack software, (Toshiba software)
I had found this bluetooth stack software on the internet, directly from Toshiba, but was reluctant installing it. It would have been valid for only thirty days.
I'm now completely interfaced with my Motorola DC800 Tx/Rx device.
I now have the house radiated with Bluetooth!
I'm happy. (I never give up)
