That's the problem with letting stuff laying 'round on your hard disk for several weeks. I'm aware of HLTIDLE, tried it, had a look at its source code...

But I found it not very effective, when run in Virtual PC. Host CPU usage was still at 50 percent, but reduced immediately, after loading IDLE.COM or EIDL.COM.

By the way: I found ROM-DOS' char output much slower than MS-DOS or FreeDOS. Maybe ROM-DOS developers didn't adapt the "every 64 characters output" behavior.
