This meant I had to fall back to looking up and using codes in the terminfo database using tigetstr.  According to the PDcurses docs, these APIs are all just stubs that return an error and so I'll probably need a curses and PDcurses mapping layer from the looks of things - which is not much better than a curses and win32 mapping layer.

While ncurses does a great job of abstracting away the issues of terminal inter-operation, the Python curses package is just a thin wrapper of that C library and, as can be seen above, not truly cross-platform due to the restrictions of PDcurses.

Fredrik Lundh's console implementation
http://effbot.org/zone/console-handbook.htm
might be of interest in that case, but I think it is 'old versions
of windows only'.  But it's a different take on the abstraction 
problem.  I haven't used it for something like 15 years now, though,
so can barely remember it ...
