[ksh93-integration-discuss] Problems with stty erase <backspace>

[Bernd Finger - Sun Germany]

Glenn,

here'e a more detailed description of what I originally posted.

Problem:
 From host1, I am doing an "ssh host2". Then, I am typing "test<backspace_key>", 
as you can see in the first attachment. After that, I am typing 
"test<bs><bs><bs><bs>" so that the funny symbols can be seen better. As the 3rd 
step, I am typing "stty erase <bs>" (which I, by the way, I wish I would never 
have to do again in the final version of ksh93. But maybe that's a topic for 
another thread on this list. Seems to be a much more complex issue than I 
originally thought. For example, even with bash, after starting vi, the 
incorrectly mapped backspace key occurred although it worked fine in the shell).
