The recent series of articles in Computer Language magazine that describe
writing TSR programs with Turbo and Microsoft C states that when DOS is
waiting for a keystroke, it makes frequent calls to interrupt 28h.
Unfortunately, there is no explanation of what INT 28h does.  Ray Duncan's
"Advanced MS-DOS" book classifies INT 28h as one of the "Reserved"
interrupts.  Can someone please shed some light on INT 28H for me?  Thanks.
