    3F8 (or 2F8 for the other port) is the ....................... holding register if written to
    and the receiver...................... register if read from. Other registers of our interest
    include 3F9 whose .................. must be set to enable received data available
    interrupt and ....................must be set to enable transmitter holding register
    empty interrupt. Bit 0 of 3FA is set if an interrupt is pending and its bits 1-3
    identify the cause of the interrupt. The three bit causes are as follows."
