Hi,

Thanks for the reply.  I had tried that, but it seems to have no effect. 
  If I type C-v Backspace I still get ^H...

~$ stty -a | grep erase
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
~$ ^H

I believe that just tells the terminal what to do on the line when it 
receives ^?, but it this case it is not, it's getting ^H.  I need to 
remap the key at a lower level, but hopefully still in Cygwin, not in 
Windows.

~Ian
