2.7.3 INTER-FUNCTION DELAY
By default, the inter-function delay is set to zero. Specify a value, ranging from 0 to 254
in units of milliseconds, to match the computer response time of the keyboard interface.
Such delay time is inserted between every function code (0x01 ~ 0x1F) being
transmitted. The longer the delay time is, the slower the transmission speed will be.
