Really?  I just tried the following:


    $ ./python
    Python 2.2.1 (#1, Jun 25 2002, 10:55:46) 
           ^^^^^
           *****
    [GCC 2.95.3-5 (cygwin special)] on cygwin
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import TERMIOS
    /home/jt/src/python-2.2.1-1/Lib/TERMIOS.py:7: DeprecationWarning: the TERMIOS module is deprecated; please use termios
      DeprecationWarning)
    >>> 
    >>> TERMIOS.TIOCMBIS
    Traceback (most recent call last):
      File "<stdin>", line 1, in ?
    AttributeError: 'module' object has no attribute 'TIOCMBIS'

So, python-2.2.1-1 does not seem to work either.  I also tried 2.2-1 and
2.1.1-1 -- they don't seem to define TERMIOS.TIOCMBIS either.

Upon reading Modules/termios.c, we see the following:

    #ifdef TIOCMBIC
        {"TIOCMBIC", TIOCMBIC},
    #endif
    #ifdef TIOCMBIS
        {"TIOCMBIS", TIOCMBIS},
    #endif

Hence, TIOCMBI[CS] will only be defined if a header files (e.g.,
sys/termios.h) defines the corresponding constants.

I'm sorry but if this is important to you, then you will have to debug
this corner case further yourself.  AFAICT, there have not been any
changes to Cygwin Python is this area for sometime (i.e., for over 1
year).
