Solution
Connect the EFOY unit to a functional battery.

Chapter 4.3 Setting Up the Terminal Program.

allocated port (such as COM 1).
Check whether a connection has been established by
the terminal program.
If using a USB-RS232 adapter:
Make sure you have the correct COM port allocation (it
generally isn't a COM1 port). You can check the port in
your PC's Device Manager.
Check whether the USB adapter has been properly
installed and the PC recognizes it.
Enter commands only in upper case, i.e. SFC, and make
sure that you have spelled them correctly (see Chapter

Make sure that the desired value is within the
