Int 21H, AH=44H, AL=0BH

3.1 and higher

SET SHARING RETRY COUNT

AX = 440Bh
CX = pause between retries (default 1)
DX = number of retries (default 3)

CF clear if successful

CF set on error
    AX = error code (01h) (see #01680 at AH=59h/BX=0000h)

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
