These functions are based on insb/insw/insd assembly input commands and outsb/outsw/outsd output commands. ReadPortBuffer - reads a number of bytes, words, or double words from the specified port address into a buffer. WritePortBuffer - write an array of bytes Remember, these functions don't provide another exchange algorithm ("handshaking"). They are used only for devices with hardware support of group input/output operations.
