FWIW, I don't see this behaviour with Python 2.6.5 on Linux. If I change
the tty settings from within an interactive Python session, they stay
changed. The only reference to tcsetattr() I can find in the Python source
code is in the termios module.
I suspect that it may be related to the "readline" module. My Python is
built with readline support (I normally use XEmacs' comint-based modes
rather than e.g. xterm, and readline either doesn't help or gets in the
way). Also, the implementation of the readline module is platform-specific:
<http://docs.python.org/library/readline.html>
The readline module defines a number of functions to facilitate
completion and reading/writing of history files from the Python
interpreter. This module can be used directly or via the rlcompleter
module. Settings made using this module affect the behaviour of both the
interpreter's interactive prompt and the prompts offered by the
raw_input() and input() built-in functions.
Note: On MacOS X the readline module can be implemented using the
libedit
library instead of GNU readline.
