It then assumes that the baud rate is not set properly and it tries to automatically detect the baud rate of the interface
and configure the host computer with the same baud rate. It assumes that the interface is turned off or improperly
connected if it fails to determine the baud rate.
Once communication has been established with the IQ interface, Turbo begins a roll call. During a roll call, Turbo
conducts a poll to identify the Crown Bus loops present and to establish communication with all IQ components. As
the roll call progresses, the screen displays the loops and devices responding to the poll.
During the roll call, Turbo also determines the settings of all IQ components and stores them into memory. It then
enters the settings into the appropriate control blocks and, when appropriate, sub-blocks. The screen in Figure
2.11 shows the typical results of a successful roll call. Notice that the screen indicates the type of interface that was
found—in this example, an IQ Interface 2. The lower section of the screen includes a tally of the number and type
of devices that responded to the roll call.
Fig. 2.11 A Typical Roll Call
A roll call can be stopped at any time by pressing q or X. Pressing the “Space Bar” will force the roll call to
advance to the next loop.
There are several parameters (system controls) that control both communication with the IQ interface and the way
a roll call works. These parameters are located on the Control Panel screen (discussed next).
