Ctrl-C doesn't work in the shell

[Chan Kim]

Hi,
When I'm on a sheel on LCD using USB keyboard, all works fine (except another important problem..)  but Ctrl-C key doesn't work.
When I press ctrl-C,  '^C' is displayed on the screen (prompt line), but doesn't have the effect of killing the job. For example, I start ping and it displays the response every second, but even if I press Ctrl-C, it contiues pinging. What should I do?
Thanks!
Chan
