HOME and END keys insert ~

["jhc0033@gmail.com" <jhc0033@gmail.com>]

I'm running Cygwin's Emacs in rxvt (no X, or screen right now). HOME
and END keys don't work in Emacs - they just insert ~. These keys work
in bash and Vim, so this looks like an Emacs problem. I did M-x
describe-bindings, and <home> is set correctly to go to the beginning
of a line. Why doesn't it work?!

C-h doesn't work either, but I don't use it so much, I can just type
"M-x help".
Also, I wouldn't mind getting F1-F12 to work.
