Backspace closes connection.

[sastephe]

Hi I have been running the sample code but when I type a backspace the connection closes with a TypeError. I was wondering if I could be given a hint on how I may want to fix this. Thank you for your help. Sam

This is the traceback that I get when I try to use the backspace ...
