i tryed
print term_conf
and i saw that the term_conf is actually represent with an array in
python:

zsh/3 4201 [1] % python test.py
[27906, 5, 1215, 35387, 15, 15, ['\x03', '\x1c', '\x7f', '\x15',
'\x04', '\x00', '\x01', '\xff', '\x11', '\x13', '\x1a', '\xff',
'\x12', '\x0f', '\x17', '\x16', '\xff', '\x00', '\x00', '\x00',
'\x00', '\x00', '\x00', '\x00', '\x00', '\x00', '\x00', '\x00',
'\x00', '\x00', '\x00', '\x00']]

it's a array of 7 elements, with the seventh element it self a array,
so in order to initialize them to zero, there's no other way than
modify them
one by one in a loop? is there a fonction like "memset" or "bzero" in
python?
