A device address consists of a primary address and an
optional secondary address. The secondary address is
separated from the primary address by a plus sign (+).
Only the lower five bits of each address are significant.
These bits may be in the range from 0 through 30 for
both the primary and the secondary address. Therefore,
the binary value 01100010 (decimal 98) is interpreted as
decimal 2.
The following examples all specify a primary address of
0 and a secondary address of 2. The listen address is
32, the talk address is 64, and the secondary address is 2

i.e., that device is requesting service. Before
completes, all devices are unaddressed.
