AX = 440Bh CX = pause between retries (default 1) DX = number of retries (default 3)
Return:
CF clear if successful CF set on error AX = error code (01h) (see #01680 at AH=59h/BX=0000h)
Notes: Delay is dependent on processor speed (value in CX specifies number of 64K-iteration empty loops to execute). If DX=0000h on entry, the retry count is left unchanged. This function was not supported by Digital Research's DOS Plus
