Description matt 2001-01-04 04:00:01 UTC 
in migrating a bunch of irix users to a freebsd mail server, i had to sift through lots of old .cshrc/.login settings that were incompatible.  one such was stty ek.  i'm not sure whether this is a doc bug or a bin bug..  but the man page (of course, dated 1994...) says stty ek is valid, yet it looks like this:
EFS matt@sublime ~ > stty -g
gfmt1:cflag=4b00:iflag=2b02:lflag=200005cb:oflag=3:discard=f:dsusp=19:eof=4:eol=ff:eol2=ff:erase=7f:intr=3:kill=15:lnext=16:min=1:quit=1c:reprint=12:start=11:status=14:stop=13:susp=1a:time=0:werase=17:ispeed=9600:ospeed=9600
EFS matt@sublime ~ > stty ek
stty: illegal option -- ek
usage: stty [-a|-e|-g] [-f file] [options]

works fine as i typed it in solaris2.6/7/8, irix 6.x/5.x, rhat linux..
I couldn't find ek anywhere in /usr/src/bin/stty/key.c ... ?

the relevent man page snippet looks like this:

ek          Reset ERASE and KILL characters back to system defaults.

Fix: 

if backspace isn't working properly, 'stty erase <hit backspace>' works in a pinch.
How-To-Repeat: 'stty ek'

It looks like this inconsistancy existed even in 4.4BSD-Lite. Where was
this manual page stolen from? Regardless, here is a patch to add the
described functionality:
