Transfers a byte, word or doubleword from “src” to the hardware port specified in DX.
For instructions with no operands the “src” is located at DS:SI and SI is incremented or decremented by the size of the operand or the size dictated by the instruction format.
When the Direction Flag is set SI is decremented, when clear, SI is incremented.
