Subject: pausing until a character is received

I'm struggling to figure out how to pause my script and await a single
character.  I've been using gets which works to pause but I'd like to
do it more cleanly.

My best lead has been in this ruby quiz[1], and the reference to
STDIN.getc .. however, having fumbled from a few angles, I'm still not
able to get it working the way I want.

I'd like to pause until any character is received, and be able to
gracefully rescue from an Interrupt.

The best I can do is pause on any character but ignore the interrupt.
So ^c would act like any other character.. which isn't what I want.
