An easy way to solve this is to use ConMan. It has an option to open a
standard console (so you can use fopen/fread/fetc on it) on a pre-existing
window.

This one is easy. Just send a packet to the console turning it to RAW
mode. I have a code fragment which I can post if you want. (I can't
send mail, so if someone else can, maybe we won't have to waste bandwidth.)
However, I can receive mail, and if several people would like the code,
I'll post (send me mail).
