how to map CTRL with none-letter keys

Hi

I'm having difficulties with mapping CTRL + none-letter keys

Is it possible to make a mapping for CTRL + the ( character?
Something like
imap <C-(> Hello
This doesn't work for me.

Then I thought apparently shift needs to be added
imap <C-S-(> Hello
This doesn't work either.
How to do that?

And what about mapping CTRL with the char's:
( (opening bracket)
, (colon)
. (dot)
; (semi colon)
| (pipe)

Rgds,
Jeri
