Where can I find a list of terminal ANSI codes sent by Ctrl-key sequences?

I am writing some behavioural tests for code that interacts with a terminal and I need to assert behaviour on the sequence C-p C-q (ctrl-p ctrl-q). In order to do this, I need to write the raw characters to the PTY. I have a small mapping at the moment for things like C-d => 0x04, C-h => 0x08.

Is there somewhere I can get a basic mapping of human readable control sequences, mapped to raw byte sequences for xterm?

Take the ASCII value of the character (e.g., for ^H, take 72), and subtract 64. Thus, ^H is 8.

This works for any control character. Using it, you can discover that, for example, ^@ is the NUL character and ^[ is ESC.
