Why do you assume that? Its not said anywhere, and its wrong. A string
consists only of the characters you can "see" - if python usues C
convention for 0-termination or othear means is an implementation detail
none of your concern.
> byte = chr(0x40)
> ser.write(byte)
>>> type(byte)
<type 'str'>
Its a string as well.
