ReadMode MODE [, Filehandle]
Takes an integer argument, one of the following values:
0 Restore original settings.
1 Change to cooked mode.
2 Change to cooked mode with echo off. (Good for passwords)
3 Change to cbreak mode.
4 Change to raw mode.
5 Change to ultra-raw mode. (LF to CR/LF translation turned off)
so that's basically what stty did, except portable...
ReadKey MODE [, Filehandle]
0 Perform a normal read using getc
-1 Perform a non-blocked read
>0 Perform a timed read
GetTerminalSize [Filehandle]
Returns either an empty array if this operation is unsupported,
or a four element array containing: the width of the terminal
in characters, the height of the terminal in character, the
width in pixels, and the height in pixels. (The pixel size will
only be valid in some environments.)
Under Windows, this function must be called with an "output"
filehandle, such as STDOUT, or a handle opened to CONOUT$.
so that's like xwininfo -size -id $WINDOWID; or resize

Not really, I don't want curses, I don't want to clear the screen.

Same problem. There is a function tb_select_input_mode(int mode)
but it only chooses how the <Esc> key is handled.

I've wandered alarmingly close to the "system specific flags" thread...
Thanks for your clear prompt answers!
