Actually, the command that was specified (ie: stty erase "^H") is perfectly
fine; the above command will NOT work, however, because of single-quoting
and escaping the carat -- stty will scream about that one.

However, why put this in /etc/profile?  To echo backspace, simply put ECHOE
in /etc/gettydefs.  For example, for a 9600 bps terminal, you could use:

m # B9600 HUPCL # B9600 CS8 SANE HUPCL TAB3 ECHOE IXANY # \r\nlogin: # m
                                            -----
The "m" is specified in /etc/ttys, and is used to define line behaviour
when logging in.  Including an ECHOE causes erase to be echoed.
