save2.py

#!/usr/bin/python3
# FOR TESTING use ./save2.py dev /dev/[your_device] test
# to manually read an address use ./save2.py
# to manually write to an address put a w before the address input "w1234"
# to list a range of addresses use ./save2.py list
# to diff two passes to see changes in the addresses use ./save2.py diff
#
# if your unit is a non savecair use address 101
# if you have a savecair use 1333
# as the savecair units have a different address space.
