PuTTY Cntrl Characters

Using PuTTY to talk with my PIC chip over a Serial connection. I want to recognize <CR> <Backspace> <Cursor Up> <Cursor Dwn> <Cursor left> <Cursor Right> and do the correct thing in the LCD display.

I figured this should be easy enough. Just go look at an Ascii table and use the Hex values being sent. Problem is I guess PuTTY sends more than one value for each of the cntrl char values.

Is there a list I can refer to for these values that I can modify my code with or is the answer starring me in the face?

I don't know the specifics of PuTTY's protocols, but ASCII does define escape characters - Control+key. To be more specific, ASCII 0 is Control-@, 1 through 26 (0x1 through 0x1a) are Control+the corresponding letter of the alphabet.
