not a problem, happens to all of us, and you are one of the most useful people
on this list so we won't hold it against you. :)

this is one of those things that annoys me, but i'll live with it.

i don't trust REMOTEHOST since it isn't always set, but here is something
quick off the top of my head that may work.

TTY=`tty | cut -c 6-`
who | grep $TTY | awk 'BEGIN { FS="(" } {print $2}' | cut -d . -f 1

and then just compare the output of the second line with a list of hosts and
set the erase correctly using case or ifs or whatever you want, the rest is an
excercise left to the reader.  this works for both telnet and ssh.

if someone can clean this up, i'm new to awk, so this is my best shot real
quick.

cheers,
