SCID vs PC Windows 10 DGT bluetooth board

The directions for DGT are a bit sketchy.  For hardware I've picked "input engine" instead of Novag Citrine.  Then they ask for a port, command and parameter.

I know which com port its on (directions show COM1: etc with a postfixed colon, I've tried with my port with and without colon).  For command it showed: dgtdrv2.i686 which I imagine is just for linux but I've tried with and without in windows.  I also tried the path to dgt's rabbit.  I've left the parameter as la.

I'm out of ideas  Any suggestions?

Only works for old serial hardware  (pre usb) if at all.

Someone needs to port Graham Oneill's drivers

Rats!  But thanks for the info so I can stop banging my head against the wall.  I don't understand why they don't all (Lucas, SCID etc) just use rabbit but oh well.
