    NOTES:

    Gets, reads, receives, etc. are all even numbered functions.
    Sets, writes, sends, etc. are all odd numbered functions.
    Functions that both send and receive data can be either but an attempt is made
    to use the function number that indicates the greater transfer amount.
    Functions that do not send or receive data use odd function numbers.

    Some functions are synonyms like read, receive and send, write.

    All common functions will have a code of less than 0x80.
    Unique functions to a class will start at 0x80.
    Executive Functions start at 0xA0.

    Utility Message function codes range from 0 - 0x1f
    Base Message function codes range from 0x20 - 0xfe
    Private Message function code is 0xff.
