Help. I don't know what to do next. Here's what I need: CBREAK mode!!!
How can one get such behavior from a program run in a CLI, using stdin?
Heck, forget stdio, let's use myprocess->pr_CIS! HELP! I'm *trying* to
interface a terminal to some amiga software (a screen editor for the terminal)
and this buffered I/O is driving me nuts! (or, rather, the inability to
unbuffer it.)

There's a packet to change a con: handler window into a RAW: window (and vice-versa). Chuck McManis (if my memory is correct) has released code in the past to send this packet, and it's on a Fish disk (I don't remember which one).

I'd propose that the information on where to get Chuck's raw io code (to send
the ACTION_SCREEN_MODE packet) be included in the monthly posting.
