AH = 86h CX:DX = interval in microseconds
Return:
CF clear if successful (wait interval elapsed) CF set on error or AH=83h wait already in progress AH = status (see #00496)
Note: The resolution of the wait period is 977 microseconds on many systems because many BIOSes use the 1/1024 second fast interrupt from the AT real-time clock chip which is available on INT 70; because newer BIOSes may have much more precise timers available, it is not possible to use this function accurately for very short delays unless the precise behavior of the BIOS is known (or found through testing)
