Operating System(s): ALL
When trying to run the software, the following error message is reported:
No serial communication ports are free
The Digital Wrench is being run for the first time and is not able to find a serial communications port to use.
Make sure there is a Serial Port available on the PC and that there are no other applications using it.
A common cause of this problem is "Hotlink" software for hand-held computers, (i.e. Palm Desktop) that hold a serial port "Open" all the time. Shut down applications like this before trying to run the diagnostic system.
