Thank you both.

Okay, ‘termios.tcgetattr’ will let me preserve the attributes, and with
Dan Sommers's suggestion of which attribute to use, I may have a shot at
setting the terminal attributes.

Then with a top-level exception handler I can clean up by restoring the
saved attributes with ‘termios.tcsetattr’.

I will investigate along those lines.
