Trying to get a old Bc785D programed for a friend but can't get a communication link between pc and scanner. They sent a 9 pin serial cable with the scanner but I don't know that it is the right one. 940-0020B is the number on the cable. I read somewhere that there is differant types of this cable. Tried using my scancontrol ver 6.11 and the uniden E-scanner software to try and get it work but no luck.
