3.2.1 Control Finite State Description
Figure 3-2 and Table 3-5 describe the Equipment Control State. The Equipment behaves differently and
will accept different messages depending on its current control state. The purpose of this diagram is to
make clear to the Host exactly what is happening at the Equipment. The logic for these states and
transitions is the logic specified in the GEM standard.
" NOTE Refer to Table 3-5 for definition of numbers used in Figure 3-2.
