Within A-Shell, the Backspace key on a PC keyboard should work just as you would expect the Rub key to work (backspace-space-backspace.) However, if you work at the UNIX prompt with a terminal emulator, you may find that the backspace key terminates the command line. This can be very frustrating. To get the Backspace key to work like you would expect (and to change the interrupt command from Backspace to Ctrl+C) try typing the following commands (or adding them to your profile.):

$ stty intr \^C

$ stty erase \^?

$ stty echo
