For completeness I will note that Windows is completely different. The
plain exit status (1 for typical command failures) appears in the
os.system result rather than a wait-encoded value. And, incidentally, an
MSVC program which calls abort() will return an exit status of 3. A
process that terminat

That's backwards. The signal (or

Here are the lines:
if os.system('modprobe --first-time -q w1_gpio') ==0
if os.system('modprobe -q w1_gpio') == 256:
I know what the 'modprobe...' is, it
