Which chip is used in your USB/RS232 cable ? If you've got a cable with the "wrong" chip, there are often troubles with this kind of cables.

Best expererience will be made with a FTDI chip and the appropriate drivers.

After installing the drivers and inserting the cable, the device manager will report the new cable and you should recognize the new assigned COM port. This must match with the COM port for your ABUS, otherwise change it.

Good luck !
