2.4 Setting Turbo’s System Parameters
The general system controls of Turbo are located on the Control Panel screen shown in Figure 2.12. It is often
necessary to make changes to these settings the first time you run Turbo because the default settings may not be
correct for your system’s host computer. From a Control Block screen, press
) to go to the Control Panel screen.
Fig. 2.12 Control Panel Screen
Use T or S+T to move the focus from one control to the next. (T advances to the next control and
S+T returns to the previous control.) Use the “Space Bar” to change an on/off control such as the Port Active
control or activate a button control like the Roll Call button. Use
Q R to change the selection of an either/or control
like the Display control. Many of these controls can also be set with a mouse ({).
Serial Port: Sets the serial or com port that Turbo will use to communicate with an IQ interface. This is usually
serial port 2 because most computers have a serial mouse connected to serial port 1. Changing the serial port
number will automatically cause a new base address and interrupt to be selected.
Base Address: Sets the base address in memory where Turbo must access the serial port. Normally you can
accept the default. If necessary, a different base address can be entered.
Interrupt: Sets the system interrupt used by the serial port. Normally you can accept the default. If necessary,
a different interrupt number can be entered.
Baud Rate: Sets the first speed that Turbo will attempt to use to communicate with the IQ interface. However,
Turbo has an “auto baud detect” feature and will automatically change the baud rate of the host computer if it fails
to communicate with the IQ interface at the baud rate you selected. In this way, the baud rate control also serves
as a baud rate indicator, showing the baud rate currently being used.
The baud rate of the host computer must match the baud rate of the IQ interface. Although some IQ interfaces can
support speeds as high as 38400 baud, some serial cables and some host computers cannot go this fast. The
device with the lowest maximum baud rate will set the maximum possible baud rate for your system. For example,
if the serial port of your host computer can only go as high as 9600 baud, you will have to set the IQ interface to
