Where did cu go?

[Nick Guenther]

In the last release I was used to using cu to talk to the gsm modem
directly, but now it seems that cu is not there! I found
http://lists.linuxtogo.org/pipermail/openembedded-commits/2007-August/007970.html
which shows it being removed from "task-openmoko-debug" but not put
back anywhere else.

I tried using `screen -l /dev/ttySAC0` but it just hung (just the
program, not the phone).

Can anyone help Where do I get cu?
