vbscript CSCRIPT howto : writie to screen and read from keyboard ?

Hello all,

I know that I can use wscript.stdout.write(line) (or just wscript.echo) and 
wscript.stdin.read(line) for that.

The problem is that I need it to happen even when the script has its 
standard input/output redirected (imagine a console-based "do you want to 
continue (YN)" interaction)

Using Win32 I can just open "CONIN$" and "CONOUT$", but I can't get those to 
work using OpenTextFile / CreateTextFile.

Any ideas ?
