I am writing a program to run in a DOS command shell (please don't tell me to switch to linux :) - I want to add functionality to display a progress report when the user presses [SPACEBAR], and increase verbosity when user presses [V], decrease it when they press [SHIFT] + [V]. This functions similarly to nmap if you're familiar.

I can't get the process to run silently until a keypress, it either waits for a keypress each loop, or it just ignores them until the end.

I've tried Term::Readkey with no luck.
In previous programs I've caught SIG{INT}, but apparently that only registers with [CTRL]+[C].

For clarity, the basic structure would be this:

While (1) {
   # Do work here... 

   $keyPressed = CatchTheInput(); # This is where I'm stuck
   if( $keyPressed =~ /[Vv]/ ){ $verbosity++; }
   if( $keyPressed == spacebar ){ GiveProgressReport(); }

}
