Their assignment is evident from names and requires no comments. GetPortByte - read a byte from a port GetPortWord - read a word from a port GetPortLong - read a double word from a port SetPortByte - write a byte to a port SetPortWord - write a word to a port SetPortLong - write a double word to a port
