That would be me, since I'm the author :-) I assume you sent it to my 
(old) usa.net address, I'll check my inbox there.

kH is the "last-line" key according to FreeBSD's termcap(5). What is the 
OS you are using, what is the tty type, and on what hardware? (please 
mail me the termcap entry for your tty)

"last-line" for going to the end of a line seems a bit strange, but if 
that is what your tty sends when you hit the End key... I could fall back 
to kH if there is no @7 defined.

What kind of OS are you using? I can use "login" under solaris and 
freebsd without any problems.

Nope. When you use vrl, ^L redisplays the line, useful in case it got 
garbled by the output of some background process. Note also that vrl is 
about lines, it doesn't (want/need to) know about the screen. The unix 
'clear' command handles that very well.
