Quite likely (depends on the driver receiving the request).  But that 
influences *all* communication with that particular device *even after you 
close the program changing that flag*.  IOW, don't do it.

Thats the one you will still need to use, unless 4402 will actually return 
an entered key (never used it, so I'm not sure).   Its also the simpelest 
one to use,

And as you do not want the input to be buffered (only returned after the 
"enter" key is pressed) you will have to handle the backspace and any other 
"undesirable" (control) characters yourself ...
